System compatibilityIC695NIU001-AH belongs to GE Fanuc PACSystems RX3i I/O family. Compatible with RX3i CPU, power supply and other RX3i I/O modules. It can be used for remote I/O rack control and network data transmission, widely used in power, water treatment and factory automation systems.

FunctionIC695NIU001-AH is Ethernet network interface unit for RX3i PACSystems. It connects RX3i rack to Ethernet network and provides RS232 and RS485 serial interfaces for field instruments. It supports optional local logic program running independently. Battery-backed RTC keeps time when power loss, and supports firmware upgrade on site. AH revision optimizes internal electronic components for better long-term stability under continuous operating temperature. It is commonly used as remote rack network adapter for distributed I/O systems.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power. Insert IC695NIU001-AH into RX3i backplane slot and lock retainer. Install backup battery for RTC. Connect Ethernet and serial cables as required. Configure network parameters, serial protocol and local logic in Proficy Machine Edition. Power on and verify network and serial communication.

InterfaceRX3i backplane gold-edge connector,Ethernet RJ45 port,RS232 port,RS485 port,on-board OK / RUN / FAULT / LINK / ACT LED indicators for GE Fanuc IC695NIU001-AH.

DiagnosticNo Ethernet communication:Check network cable,IP address setting or link status. Serial communication failure:Baud rate mismatch, wrong protocol or cable wiring fault. FAULT LED lit:RTC battery low, memory error or backplane communication fault.
