SCMD digital input modules provide highly reliable and safe interfaces to harsh industrial measurement and control applications. With SCMD modules installed near individual field signals, a reliable isolation barrier is provided between the field wiring computer system. Other benefits include reduction of field wiring costs and establishment of a cost effective and manageable method for system expansion and repair.
The SCMD-MIAC digital input modules are used for sensing ON/OFF AC or DC voltage levels in the ranges of 18-36, 90-140 and 180-280VAC or VDC respectively. They are protected from damage due to high-voltage transients on the input signal.
The SCMD-MIDC digital input modules provide DC voltage sensing at the lower ranges of 3.3 to 32VDC and 10 to 60VDC.
High voltage, low voltage, fast switching, and low noise options are available, designated by suffixes "A", "E", "F", and "N" respectively.
Five backpanels are available for mounting SCMD-M digital input modules.
