Product Introduction
The GE IC695NIU001 is a Network Interface Unit (NIU) used in the PACSystems RX3i family. It allows a remote I/O rack to operate as an intelligent node on a PROFINET or Ethernet network, facilitating high-speed, distributed I/O and modular control. Designed to deliver performance, flexibility, and scalability, it provides efficient I/O communication without requiring a local CPU. The NIU architecture allows for reduced system cost while maintaining high reliability and deterministic control over industrial Ethernet.
The IC695NIU001 supports PROFINET communication via integrated ports or with the addition of an Ethernet daughtercard. It is compatible with a broad range of RX3i I/O modules, offering integration into many industrial automation processes where centralized or distributed control is essential.
