                                                                            IC695ECM850 is a dedicated gigabit Ethernet communication module for Emerson PACSystems RX3i PLC (formerly GE Fanuc). It is specially designed for power grid substation automation, acting as an IEC 61850 client gateway to connect RX3i controllers with substation IED protection relays. It integrates a built-in 4-port managed gigabit switch, supporting both copper and fiber optical networking, far more powerful than general IC695ETM001 single-port Ethernet modules, and supports hot-swap operation for non-stop maintenance.
