GE Fanuc IC695CMM004 Serial Communications Module

The GE Fanuc IC695CMM004 is a 4-port serial communication module for PACSystems RX3i PLCs. It supports RS-232/422/485 interfaces and protocols like Modbus and DNP3. This high-density module features 500VDC port isolation and provides scalable connectivity for complex industrial networks.

The IC695CMM004 serves as a high-capacity serial interface for the PACSystems RX3i controller platform. This module provides four independent ports for bidirectional data exchange between the CPU and external industrial devices. Each port utilizes an RJ45 connector and operates separately to maximize system throughput. Furthermore, the module supports a wide range of standard protocols including Modbus Master/Slave and DNP3. It effectively bridges the gap between modern PLC control and legacy serial-based field equipment.
