IC695NIU001 GE Fanuc PACSystem RX3i Ethernet NIU Communication Module

IC695NIU001 RX3i Ethernet Network Interface Unit

IC695NIU001 is a high-performance Ethernet Network Interface Unit engineered for the PACSystems RX3i automation platform.

The module enables intelligent communication between RX3i systems and legacy Series 90-30 I/O infrastructures.

Its hybrid backplane architecture simplifies industrial migration projects while maintaining stable Ethernet-based data exchange.

The integrated serial communication interfaces also provide flexible field-level connectivity for industrial devices and supervisory systems.

Global PLC Spare HUB's Insight

IC695NIU001 remains a practical solution for engineers upgrading existing Series 90-30 systems without replacing complete field architectures.

The dual-backplane capability significantly reduces migration complexity in brownfield automation projects.

Its integrated Ethernet Global Data functionality improves deterministic communication between distributed process nodes.

This module is especially valuable in facilities requiring mixed-generation PLC integration and long operational lifecycle planning.
