SCMD-MOAC/MODC

Miniature Digital Output Modules

Description

The SCMD digital output modules are used for switching AC and DC loads such

as relays, solenoids, motor starters, or indicator lamps. All models provide up

to 4000Vrms of optical isolation between the field device and the control logic.

The AC output modules incorporate zero voltage switching and an RC snubber

circuit which allows switching heavy inductive loads. Functionality is denoted

by case color—AC modules are black, and DC modules are red.
Six backpanels are available for mounting SCMD-M digital output modules. See

“Accessories” section .
