                                                          Overview

                                                          IC695CMM004 is a 4-channel isolated serial communication module for Emerson PACSystems RX3i PLC (formerly GE Fanuc). It expands serial communication capacity for the RX3i rack, enabling data exchange between the RX3i CPU and third-party instruments, protection relays, remote RTUs and SCADA systems. All four ports are independently configurable with electrical isolation to resist industrial electromagnetic interference, supporting multiple mainstream industrial serial protocols for power and process automation.
