The GE IC695NKT002 is an Ethernet Network Interface Unit (NIU) Kit for the PACSystems RX3i series of Programmable Logic Controllers (PLCs). Its purpose is to enable remote I/O on an Ethernet network. The kit includes the two essential modules required for this function.
Kit Contents
The IC695NKT002 is a pre-packaged solution to simplify ordering and ensure a complete assembly for an Ethernet-based remote I/O station. The kit includes:
- IC695NIU001 Network Interface Unit (NIU): This module is the “brain” of the remote I/O station. It manages the communication with the main PLC and controls the I/O modules in its local rack. It also has two built-in serial ports (RS-232 and RS-485) and 20K of optional local logic memory. The NIU occupies two slots on the universal backplane.
- Two (2) IC695ETM001 Ethernet Modules: These modules provide the physical Ethernet ports (10/100 Mbps) for the NIU. They connect the remote I/O station to the main PLC’s network via Ethernet. Each ETM module occupies one slot, so the kit requires a total of four slots on an RX3i universal backplane.
The NIU and ETM modules work together to create a slave I/O station that automatically exchanges data with a master PLC using protocols like Ethernet Global Data (EGD).
Application
The IC695NKT002 kit is used for building distributed control systems where I/O points are geographically separated from the main PLC. It provides a cost-effective alternative to running long, individual wiring runs and allows for a more scalable and flexible system architecture.
