SCMD-MIAC/MIDC
Miniature Digital Input Modules
Description
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. See
“Accessories” section.
