GE IC695NIU001-CK – PACSystems RX3i Ethernet Network Interface Unit

In stock

Product Introduction:

The IC695NIU001-CK is a conformal-coated variant of the IC695NIU001 Ethernet Network Interface Unit, designed for the Emerson PACSystems RX3i PLC platform. It retains all core communication and logic features of the standard NIU while adding a protective conformal coating, making it suitable for harsh industrial environments with high moisture, dust, chemical exposure, or corrosive gases. Engineered for reliability in demanding applications, it delivers robust multi-protocol communication and distributed I/O support in conditions where uncoated modules cannot operate consistently.
