GE IC695NKT001CA RX3i Ethernet NIU Kit Conformal Coated

The GE IC695NKT001CA is an Ethernet Network Interface Unit (NIU) Kit for the PACSystems RX3i series of Programmable Logic Controllers (PLCs). The “CA” suffix indicates that the modules in the kit are conformal coated, which provides a protective layer against environmental contaminants.

Key Features

• Remote I/O: This kit allows you to set up a remote I/O station on an Ethernet network. The main PLC (master) communicates with this kit (the slave) to control and monitor the I/O modules in its rack. This is a cost-effective way to manage I/O points that are far from the main control panel.
• Conformal Coating: The “CA” suffix is the most significant differentiator for this model. The circuit boards of the included modules are covered with a thin, protective polymer film. This coating safeguards the electronics from:
  • Moisture and humidity 💧
  • Dust and airborne particles
  • Corrosion caused by chemicals or salt spray 🧂
• Kit Contents: The kit is a complete solution, including the two essential modules for the remote I/O station:
  1. IC695NIU001 (Network Interface Unit): This is the brain of the remote station. It manages communication with the main PLC and provides 20K of optional local logic, allowing for some processing at the remote location. It occupies two slots on the backplane.
  2. IC695ETM001 (Ethernet Module): This module provides the physical Ethernet port (10/100 Mbps) for connecting the NIU to the network. It occupies one slot.
• Communication Protocols: The modules support standard industrial Ethernet protocols like Ethernet Global Data (EGD), SRTP, and Modbus TCP/IP. This ensures compatibility with a wide range of GE and third-party equipment.

Applications

The IC695NKT001CA is an ideal solution for building distributed control systems in harsh environments. It’s commonly used in:

• Chemical plants and paper mills where corrosive vapors are present.
• Food and beverage facilities where washdowns and high humidity are common.
• Marine and offshore platforms where equipment is exposed to salt spray and moisture.
• Any application where the remote I/O station needs robust protection against environmental factors.
