Description
SCM7B31-01D Dataforth input module provides a single channel of analog input which is filtered, isolated and converted to a high-level voltage output. The units compact package saves space and is ideal for high channel density applications.
Each SCM7B21/30/31 voltage input module accepts one channel of analog voltage input which is filtered, isolated, amplified, and converted to a high-level analog voltage for output to the process control system.
Modules accept a wide 14 – 35VDC power supply range (+24VDC nominal). Their compact packages (2.13″x1.705″x0.605″ max) save space and are ideal for high channel density applications. They are designed for easy DIN rail mounting using any of the “-DIN” backpanels.
