GE IC695NIU001-CK Ethernet Network Interface Unit

Network Architecture and Communication Capabilities

The GE IC695NIU001-CK serves as a high-performance Ethernet network interface unit for the PACSystems RX3i platform. It provides a direct connection between remote I/O racks and the main controller over standard Ethernet networks. This unit supports 10/100 Mbps auto-negotiating communication speeds for flexible network integration. It features two independent Ethernet ports that support daisy-chain or ring topologies without requiring external switches.

Engineers can deploy this interface unit to distribute I/O across large facilities efficiently. The embedded web server allows users to monitor diagnostics, configuration, and status through any standard browser. Consequently, maintenance teams can access critical system information without installing specialized software.

Physical Specifications and Mounting

The IC695NIU001-CK measures 14.0 cm in height, 4.5 cm in width, and 13.2 cm in depth. It weighs approximately 0.45 kg, making it suitable for high-density control cabinets. This unit mounts directly onto a standard RX3i Universal Backplane alongside CPU modules and I/O carriers. The front panel includes LED indicators for power, network link activity, and module status. These visual cues provide immediate feedback during startup and troubleshooting procedures.

Power Requirements and Energy Storage

This network interface unit draws 550 mA from the backplane at 3.3 VDC for normal operation. It incorporates energy storage capacitors that maintain operation during momentary power fluctuations. These capacitors provide sufficient hold-up time to preserve network connections during brief supply interruptions. The unit also features a real-time clock with a lithium battery backup to retain time and date settings when the system loses power.

Technical Specifications

Remote I/O Expansion and System Integration

The IC695NIU001-CK supports up to 64 I/O modules across multiple expansion racks in a remote configuration. It communicates seamlessly with RX3i CPUs and VersaMax remote I/O systems through Ethernet networks. Users can configure the unit using Proficy Machine Edition software for straightforward setup and diagnostics. This flexibility makes the IC695NIU001-CK ideal for distributed control architectures in manufacturing and process industries.
