The GE IC695NKT001 is an Ethernet Network Interface Unit (ENIU) kit designed for the PACSystems RX3i platform, used to enable remote I/O expansion over Ethernet networks.
It allows distributed I/O racks to communicate with a central controller via Ethernet, making it ideal for large-scale, geographically distributed automation systems. The module integrates both a network interface unit (IC695NIU001) and an Ethernet communication module (IC695ETM001) into a single solution.
This makes it a key component for building distributed PLC architectures, reducing wiring complexity and improving system scalability.
