GE IC695LRE001 Expansion Modules for Local and Remote I/O
Programmable ControllersThe RX3i supports various expansion options for local and remote I/O to optimize
configurations. The RX3i can be expanded up to 8 expansion bases using local remote
expansion module. The RX3i also supports Ethernet remote I/O using the RX3i Ethernet
Network Interface module (IC695NKT001) Series 90-30 Ethernet Network Interface module
(IC693NIU004) for more distributed I/O.
