Communications Coprocessor Modules | GE IC693CMM311G

The General Electric IC693CMM311G is a Communications Coprocessor Module engineered for modular GE Series 90-30 programmable controller systems. This single-slot hardware unit provides two dedicated serial communication ports supporting RS-232 applications to expand network connectivity and facilitate data exchange between the CPU and peripheral industrial devices.

Hardware Architecture and Slot Assignment

Designed for baseplate mounting, the module occupies a single slot and can be installed in any available backplane slot except the dedicated CPU slot. Systems can integrate up to four communication coprocessor modules depending on application scale and backplane power limits.

Diagnostics and Power Specifications

Onboard status LED indicators provide quick visual verification of module health and serial activity, featuring dedicated lights for Module OK, PORT1, and PORT2. The unit draws 400 mA of backplane current from the +5 VDC system bus.
