indication

At the appropriate input level (>8.5 V), the opto decoupled input in the
SSRPC will switch on a power transistor to connect the load to the
plus pole of the load circuit supply (U

The transistor will switch off when

- the control voltage (U

) is removed

- there is a short-circuit/overload in the load circuit.

Status indication is provided by two LEDs (red and green).
Thermal-magnetic style overload protection occurs at approx.
1.5 times rated current. See time/current characteristic curves.
The SSRPC is fitted with blade terminals DIN 46244-A6.3-0.8 and is
suitable for plug-in mounting with various E-T-A sockets (see
Accessories).

Control circuit
ON condition:

If a voltage higher than 8.5 V is applied to the input terminals (-IN,
+IN), the control current (from the PLC) will flow through the opto
coupler. The output transistor will be conductive, the green LED will
be lighted.

OFF condition:

A control voltage lower than 5 V will switch the output transistor off.

Load circuit

The load circuit switches depending on the control signal (“0” or “1”).
It is electronically monitored for faults. In the event of a short-circuit
the circuit is disconnected after max. 250 µs whilst upon inadmissible
overload it is disconnected according to the time/current curves
shown.

Fault indication output

The fault indication circuit (F+, F-) is opto decoupled from the load and
control circuit.
In the OFF condition, this circuit will provide wire break indication,
with the transistor output being open.
In the ON condition, the circuit will provide short-circuit and overload
monitoring and indication.
Visual fault indication by red LED.

Description

Features

Ordering information

E-1048-7..

The E-T-A Solid State Remote Power Controller E-1048-7.. is a
transistorised switching device providing both protection and
signalisation. It is suitable for all applications where the capabilities of
the existing PLC outputs are not sufficient or where no protection
against overload and short circuit or wire breakage monitoring of
connected loads is provided. The use of a costly, high-capacity output
card becomes superfluous when only one or two powerful outputs are
necessary.

Using the SSRPC E-1048-7.. in combination with the module 17plus
creates a new, very flexible system capable of being subsequently
changed or extended. Busbars, pre-wired signal contacts and spring-
loaded terminals reduce installation times considerably (see
accessories).

The transistor will switch off when

- the control voltage (U

) is removed

- there is a short-circuit/overload in the load circuit.

Status indication is provided by two LEDs (red and yellow).
Simulated thermal-magnetic overload protection occurs at approx.
1.5 times rated current. See time/current characteristic curves.
The SSRPC is fitted with blade terminals DIN 46244-A6.3-0.8 and is
suitable for plug-in mounting with various E-T-A sockets or

Control circuit
ON condition:

If a voltage higher than 8.5 V is applied to the input terminals (+I

against GND), the control current (from the PLC) will flow through the
opto coupler. The output transistor will be conductive, status
indication by yellow LED.

OFF condition:

A control voltage lower than 5 V will switch the output transistor off.

Load circuit

Fault indication output F

The fault indication circuit is physically isolated from the load and
control circuits via a relay.
In the OFF condition, this circuit (with closed contact) will provide wire

Technical data

Module 17plus is a power distribution system for use with SSRPC
E-1048-7.. for PLC outputs.
Each module accommodates two SSRPCs with an individual housing
width of only 12.5 mm and fits onto all industry standard mounting
rails. The two-way modules can be interconnected to provide as
many ways as required with a terminal block fitted at each end for
connection of signalling circuits. A distribution busbar can be fitted
on the supply side of the modules (positive pole) though each pole of
multipole circuit breakers must be individually connected. Electrical
connections are by means of spring-loaded terminals. The reference
potential for the electronic amplifiers (GND pin 11) is also looped
through and to the terminals connected at the sides. Control of the
amplifiers (IN+), referenced to GND, is per channel via the separate
terminal 12 beside the LOAD terminal. The SSRPC has an integral signal
contact (break contact) used for group signalisation. Therefore the
terminals of all break contacts are connected in series in the module
17plus and are connected to the terminal blocks via two terminals
(13, 14). The module is designed to accommodate a probe for series
connection continuity tests. When multipole circuit breakers are fitted
auxiliary contacts are required for each pole. Individual circuit breaker
signalisation is achieved through use of the break contacts (which
close in the event of failure) connected in parallel by means of
terminals on each module. The signalling circuitry between modules
and the internal prewiring for the potential is automatically connected
when the modules are linked together.
Meets the requirements of UL60950.

The Smart Power Relay E-1048-8C.- is a remotely controllable
electronic load disconnecting relay with three functions in a single unit:

●

electronic relay

●

electronic overcurrent protection

●

status indication

The 7 pin CUBIC version is designed for use with standard automotive
relay sockets. A choice of current ratings is available from 1 A
through 25 A. An operating voltage range of DC 9...32 V allows the
connection of DC 12 V and DC 24 V loads.

In order to switch and protect loads remotely, it has until now been
necessary to connect several discreet components together

- an electro-mechanic relay, control cable and integral contact

to close the load circuit

- an additional protective element (circuit breaker or fuse) for cable

or equipment protection

- a device for current measurement (shunt)

Now type E-1048-8C combines all these functions in a single unit,
thus minimising the number of connections in the circuit and
thereby reducing the risk of failures.

Applications

Type E-1048-8C. is suited to all applications with DC 12 V or DC 24 V
circuits, where magnetic valves, motors or lamp loads have to be
switched, protected or monitored:

- road vehicles (utility vehicles, buses, special vehicles)
- rail vehicles
- marine industry (ships, boats, yachts etc.)

The Power Relay is also suitable for industrial use (process control,
machine-building, engineering) as an electronic coupling relay between
PLC and DC 12 V or DC 24 V load

with e1 appr

oval

●

Integral power electronics provide a wear-resistant switching
function, insensitive to shock and vibration.

●

Only a fraction of the control power needed by electro-mechanical
relays is required for switching loads. This is important for battery
buffered load circuits which have to remain controlled even with
the generator off line.

●

The extremely low induced current consumption of less than 1 mA
is absolutely necessary for battery buffered applications.

●

The load circuit is disconnected in the event of an overload or
short circuit, the trip curve is also suitable for smaller motor loads.

●

The load circuit is permanently monitored for wire breakage.

●

Two status outputs for control signal AS and group signal SF
provide status indication. For processing the actual value of the
current flow in a power management system an analogue output
from 0 to 5 V is provided. This voltage signal may also be used as
an input to a control circuit or to switch off the unit by means of
external control in the event of low load current value.

●

For switching and monitoring loads of 25 A plus it is possible to
connect several units in parallel. Uniform power distribution between
units must be ensured by symmetrical design of the supply cables
(length and cross section).

●

The Smart Power Relay E-1048-8I.- is a remotely controllable electronic
load disconnecting relay with three functions in a single unit:

●

electronic relay

●

electronic overcurrent protection

●

status indication

The 7 pin INLINE version is designed for use with various E-T-A
terminal blocks, e. g. 17-P10-Si. A choice of current ratings is available
from 1 A through 20 A. An operating voltage range of DC 9...32 V
allows the connection of DC 12 V and DC 24 V loads.

In order to switch and protect loads remotely, it has until now been
necessary to connect several discreet components together:

- an electro-mechanic relay, control cable and integral contact

to close the load circuit

- an additional protective element (circuit breaker or fuse) for

cable or equipment protection

- a device for current measurement (shunt)

Now type E-1048-8I. combines all these functions in a single unit,
thus minimising the number of connections in the circuit and
thereby reducing the risk of failures.

Applications

Type E-1048-8I. is suited to all applications with DC 12 V or DC 24 V
circuits, where magnetic valves, motors or lamp loads have to be
switched, protected or monitored:

- road vehicles (utility vehicles, buses, special vehicles)
- rail vehicles
- marine industry (ships, boats, yachts etc.)

The Power Relay is also suitable for industrial use (process control,
machine-building, engineering) as an electronic coupling relay
between PLC and DC 12 V or DC 24 V load

●

Integral power electronics provide a wear-resistant switching
function, insensitive to shock and vibration.

●

The extremely low induced current consumption of less than 1 mA
is absolutely necessary for battery buffered applications.

●

The load circuit is disconnected in the event of an overload or
short circuit, the trip curve is also suitable for smaller motor loads.

●

The load circuit is permanently monitored for wire breakage.

●

For switching and monitoring loads of 20 A plus it is possible to
connect several units in parallel. Uniform power distribution between
units must be ensured by symmetrical design of the supply cables
(length and cross section).

●

Solid State Remote Power Controller E-1071-073

In principle, the E-T-A SSRPC E-1071-073 operates like conventional
electro-mechanical relays, with additional protective and signal
functions. The control input replaces the magnetic coil and the power
transistor replaces the main contact.

Control circuit

The control current flows through the LED and the opto coupler
immediately a voltage higher than 8.5 V (= control signal “1”) is
applied at the input terminals (6 and 7). The opto coupler transmits the
signal to the load circuit, at the same time switching the load
transistor on. This signal is transmitted as a status signal to all
monitoring circuits. The input protection diode protects the control
voltage from incorrect polarization. Control current limitation is
provided by a constant current diode.

Load circuit

The load circuit is switched ON or OFF according to the control signal
(“0” or “1”), with electronic circuits monitoring the load circuit for faults
such as overload or short-circuit. Should one of these faults occur, the
monitoring circuitry will immediately react, causing the load transistor
to disconnect and the circuit breaker to trip. Transistor disconnection
occurs according to the storage time characteristics. The storage time
increases noise immunity avoiding disconnection of non-harmful
peaks such as those caused by inrush currents from lamp load
connection. Storage time is not a constant quantity but is inversely
proportional to the overcurrent factor.

Status indication

Status indication is provided by 2 LEDs (yellow and green) on the front
of the housing.

YELLOW LED = correct control voltage

The LED indicates when the control voltage is
higher than 8.5 V, with control current flowing.

GREEN LED = correct load current

The green LED indicates when the load current is
higher than 0.2 A.

Faults such as too high a load resistance, wire break, poor contact, or
overload/short-circuit, are available when only the yellow LED
indicates. SSRPC E-1071-073 includes two current measuring
terminals (2 mm dia.) on the front. These terminals provide for load
current measurement in terms of voltage drop at the 0.1 Ω shunt in the
load circuit.

In principle, the E-T-A SSRPC E-1071-128 operates like conventional
electro-mechanical relays, with additional protective and signalling

ON and fault indication outputs have more complex functions and
may not be compared with auxiliary contacts.

Load circuit

Signal circuit
The signal circuit includes two opto couplers signalizing either correct
ON duty or a fault. These signals may be computer processed.
- The ON signal output indicates correct operating in the ON condition.

This output is conductive

when control voltage is available

AND the load current is higher than the set minimum current
AND the circuit breaker has not tripped
AND there is no wire break.

- The fault signal output signalizes the fault source which must be

eliminated. This output is non-conductive when

the circuit breaker has tripped on overload or short-circuit

there is a wire break

control voltage is available AND the minimum current has not
been reached

no control voltage is applied although the load current is
available.

The fault signal output operates on the closed-circuit principle, i.e. it
carries plus potential during fault-free operation.

allows the connection and disconnection of the load outputs of two
channels independent of each other.

Control circuits (I/II)

The control current flows through the LED and the opto coupler
immediately a voltage higher than 8.5 V (= control signal “1”) is
applied at the input terminals (6 and 7, or 10 and 7). The opto coupler
transmits the signal to the load circuit, at the same time switching the
load transistor on. This signal is transmitted as a status signal to all
monitoring circuits. The input protection diode protects the control
voltage from incorrect polarization. Control current limitation is
provided by a constant current diode.

Load circuits (I/II)

After expiration of the storage time (see diagram) the load circuit
transistor will become non-conductive. After approx. 5 s the isolator
will switch off so as to disconnect the two load circuits. The common
auxiliary contact closes signalling the fault. After removal of the fault,
the SSRPC can be reactivated by pushing the isolator button.

Status outputs

Status indication is provided by 4 LEDs (2 x RED, 2 x GREEN).

RED LED
ON indication (I/II)
The red LED indicates when the control voltage is higher than 8.5 V,
with control current flowing.

GREEN LED
Current flow indication (I/II)
The green LED indicates when the load current is above 0.1 A.

Faults such as too high a resistance, wire break, poor contact, or
overload/short-circuit, are available when only the red LED indicates.

The SSRPC E-1071-343 includes three current measuring terminals
(4 mm dia.) on the front. These terminals provide for load current
measurement in terms of voltage drop at the 0.1 Ω shunt in the load
circuit (I/II).

- 49

E-1072-100

Description

The E-T-A Solid State Remote Power Controller E-1072-100 is a
double pole electronic switching amplifier suitable for resistive and
inductive loads (solenoids, magnetic brakes etc.) as well as for lamp
loads and capacitive loads.

The double pole electronic switching output eliminates
inadvertent start-up or dangerous machine movements as may
arise upon a ground fault in systems with ungrounded power
supply (‘IT systems’) (see Machinery Directive EN 60204 part 1,
para. 9.4.3.1).

Typical applications

●

Two pole actuator switching for machinery and plants.

●

Monitoring of the electrical functionability of these loads.

●

In-rush current limitation of lamp and capacitive loads.

●

Protection of load circuit cables.

●

ON and fault indication (by LEDs or RED trip button) and
signalling (via potential-free auxiliary contacts).

●

Two pole physical isolation upon overload or when tripped
manually.

Features

●

PLC controllable electronic switching amplifier (max. 3 A) with
additional protective and control functions for DC 24 V loads (e.g.
solenoids, magnetic brakes, electromagnetic clutches, monitoring
and indicator lamps).

●

Overload and short-circuit proof double pole switching output with
in-rush current and short-circuit limitation.

●

Electronic disconnection upon
- an overload in the load circuit,
- short-circuit in the load (load+/load-, load+/-U

, and

load-/+U

), followed by 2-pole isolation of the load circuit

(via relay contacts).

●

Control input “In/Ctrl” with control current indication (YELLOW LED).

●

“O.K.” and availability indication (GREEN LED).

●

Short-circuit and overload indication (fault indication F and RED LED).

●

“Err1” group fault signalisation – all faults will be signalled:
- wire breakage in the load circuit
- earth fault at switching output
- internal faults
- overload or short circuit in the load circuit

●

“Err2” fault signalisation:
- only overload or short circuit in the load circuit
- reset required

●

Integral protection against reverse polarity and overvoltage for the
control and load circuit.

Solid State Remote Power Controller E-1072-CF2

Issue B

- 57

E-1072-CF2-..

Description

The E-T-A Solid State Remote Power Controller E-1072 is a double
pole electronic switching amplifier suitable for resistive and inductive
loads (solenoids, magnetic brakes etc.) as well as for lamp loads and
capacitive loads.

The double pole electronic switching output eliminates
inadvertent start-up or dangerous machine movements as may
arise upon a ground fault in systems with ungrounded power
supply (“IT systems”) (see Machinery Directive EN 60204 part 1).

Typical applications

Technical data (T

ambient

= 25 °C, U

= DC 24 V)

●

Two pole actuator switching for machinery and plants.

●

Monitoring of the electrical functionability of these loads.

●

In-rush current limitation of lamp and capacitive loads.

●

Protection of load circuit cables.

●

ON and fault indication (by LEDs or RED trip button) and
signalling (via potential-free auxiliary contact).

●

Two pole physical isolation upon overload or when tripped
manually.

Features

●

PLC controllable electronic switching amplifier (max. 3 A) with
additional protective and control functions for DC 24 V loads (e. g.
solenoids, magnetic brakes, electromagnetic clutches, monitoring
and indicator lamps).

●

Overload and short-circuit proof double pole switching output with
in-rush current and short-circuit limitation.

●

Electronic disconnection upon
- an overload in the load circuit,
- short-circuit in the load (load+/load-, load+/-U

, and load-/+U

followed by 2-pole isolation of the load circuit (via relay contacts).

●

Control input with control current indication (YELLOW LED).

●

OK and availability indication (GREEN LED).

●

Short-circuit and overload indication (fault indication F and RED LED).

●

Continuous wire break monitoring of the load circuit (fault indication
F and ORANGE LED).

●

Additional supervision of the power transistors and load output
potential (e.g. ground fault) when not energized. Deviation from
required state is indicated as an internal fault (fault indication F,
RED + ORANGE LEDs).

●

Integral reverse polarity and overvoltage protection of control and
load circuits.

●

Integral fault indication F (wire break, short-circuit, overload,
ground fault, internal fault)
- switch contact (N/O) with external status indication (RED actuator

button tripped).

- internal fault storage (push RED button to reset).
