Product Overview

The IC695CMM002 is dual‑channel isolated serial communication expansion module for GE‑Emerson PACSystems RX3i PLC platform. Each RJ‑45 port is independently configurable for RS‑232, RS‑422 or RS‑485 physical layer, supporting Modbus‑RTU and multiple legacy serial protocols. Galvanic isolation between ports and backplane suppresses ground‑loop noise and transient surges in heavy‑EMI plant cabinets. It enables RX3i CPU to connect to third‑party transmitters, variable‑frequency drives, RTU and legacy serial field devices. Front‑panel LED indicators deliver instant module and channel fault feedback for rapid on‑site troubleshooting. Multiple modules can populate one rack to expand serial interface quantity for complex automation systems.

This module addresses legacy‑device integration challenges: multi‑protocol isolated serial expansion for RX3i controllers, flexible hardware‑selectable physical interfaces, drop‑in spare‑part compatibility for existing PACSystems RX3i retrofit‑maintenance projects. PLC automation engineers, power‑plant and manufacturing‑site maintenance technicians and retrofit integrators benefit most. Typical applications: water‑treatment plants, material‑processing lines, power‑plant auxiliary control cabinets, retrofitting legacy Modbus serial instrument networks.

Key Application Notes

‑RX3i rack‑mount module; cannot operate standalone. Requires RX3i universal backplane, compatible CPU (firmware V3.83 or newer) and Proficy Machine Edition configuration software ‑RJ‑45 serial ports require external adapter cables to convert to terminal‑block wiring for field instruments ‑Supports maximum 6 modules per main rack; observe total backplane current budget during system design ‑Not hot‑swap capable: rack DC power must be fully de‑energized before module replacement ‑Original OEM production active; surplus / refurbished spare parts widely available for retrofit systems ‑Conformal‑coated variants exist for high‑humidity, corrosive cabinet environments ‑Follow GE IC695CMM002 hardware manual for cable selection, bus termination resistor and protocol parameter setup
