Exchanges remote I/O data through the documented EGD architecture.
Product Overview
IC695NIU001 is Emerson’s PACSystems RX3i Ethernet Network Interface Unit for remote I/O architectures using Ethernet Global Data.
Manufacturer documentation identifies up to 1300 bytes of input data and 1300 bytes of output data, redundant-controller output support and dual-backplane operation with RX3i PCI and Series 90-30 serial buses.
The unit also provides RS-232 and RS-485 serial interfaces supporting Modbus RTU, SNP and Serial I/O functions documented for the base model.

Applications
- Distributed PACSystems RX3i I/O stations connected through EGD.
- Remote I/O nodes that must receive outputs from redundant controllers.
- Modernization that retains Series 90-30 serial-bus modules in an RX3i station.
- Replacement of an installed IC695NIU001 with a verified configuration archive.
Installation
- Export the NIU and controller hardware configuration, EGD exchanges and network settings.
- Record the rack, power budget, serial devices, remote I/O map and Ethernet topology.
- Confirm firmware and configuration-tool compatibility before downloading the station.
- Test every configured input and output, EGD exchange, redundancy path and serial connection.

FAQ
What should accompany an IC695NIU001 enquiry?
Send the full NIU label, rack and power models, firmware, configuration-tool release, EGD exchange list, network settings and required quantity.
What should be staged before replacing IC695NIU001?
Stage a verified hardware configuration, EGD producer and consumer definitions, network parameters, module map and an approved rollback plan.
How should redundant outputs be checked with IC695NIU001?
Test the approved controller switchover and confirm output ownership, timing and safe states across every affected point.
Can IC695NIU001-DN be assumed identical to IC695NIU001?
No. The DN suffix is a distinct revision identity and should be reviewed against firmware, configuration support and the installed record.
What proves IC695NIU001 is ready for service?
Confirm clean diagnostics, correct station identity, stable EGD exchanges, complete I/O testing, serial communications and the approved redundancy test.
