The IC695NIU001, produced by Emerson Automation and originally developed by GE Intelligent Platforms (GE IP), is an Ethernet Network Interface Unit designed for the PACSystems RX3i platform. Engineered for efficient data communication and system integration, it features dual RS-232 and RS-485 communication ports and supports Ethernet connectivity through a backplane-mounted Ethernet Interface Module (catalog number IC695ETM001). The unit includes 10 MB of built-in flash memory and supports firmware upgrades, ensuring long-term flexibility and compatibility with evolving automation requirements. Functioning as a communication bridge, the IC695NIU001 enables seamless interaction between PACSystems RX3i and Series 90-30 I/O modules. This interface unit may be deployed in industrial automation systems across North America, Europe, Asia, and worldwide, where reliable network performance, interoperability, and scalable control are vital for optimized system operation.
