The IC695CMM004 is a PACSystems RX3i Serial Communication Module, originally manufactured by GE Intelligent Platforms (GE IP) and now under Emerson Automation. It features four independent RJ-45 serial ports that support RS-232 or RS-485/422 communication, configurable for 4-wire (full-duplex) or 2-wire (half-duplex) operation to accommodate various serial communication needs. Up to six instances of this module can be installed in a single CPU backplane, offering scalability and flexibility for complex system architectures. Each port is individually configurable to operate as MODBUS Master, MODBUS Slave, CCM Slave, DNP3 Master, DNP3 Slave, or Serial I/O protocol, providing broad interoperability across industrial communication standards. The IC695CMM004 includes 500 VDC continuous and 710 VDC for 1-minute isolation ratings, ensuring electrical protection and signal integrity. This module may be deployed in automation systems across North America, Europe, Asia, and worldwide, where robust serial communication, multi-protocol flexibility, and dependable PACSystems RX3i integration are essential for high-performance industrial control applications.
