SCM117 Power/Comms Module

SIM117 is a mature product — see the SCM318 for new designs.

SCM117-A03 an Extended Lifetime Product.


The SCM117 is designed to complement a Generation 3 or 4 (SIM115SIM231SIM535SIM243, or SIM543) Serious Integrated HMI Module (SIM), providing RS232, RS422, or RS485 network signal and 9-25V power connectivity.

The 60-pin low profile board-to-board header docks into Generation 3 or 4 Serious Integrated HMI Module (SIMs), and the standard 3.5mm industrial screw-terminal-plug connector is a simple connection to power and the serial network.

Explore these options compared to the SCM117:
  • SCM318 for high performance and cost-effective comms & control for the latest generation HMI modules
  • SCM208 for comms/control applications with older generation 3 & 4 HMI modules

Note that new generation 5 HMI modules include the SCM117 functionality built-in!
