Provides an EGD-based remote I/O station using the documented NIU base architecture.
Product Identification
IC695NIU001-DN is the DN hardware execution of Emerson’s PACSystems RX3i Ethernet Network Interface Unit. The suffix is retained as a revision boundary.
The base NIU architecture exchanges remote I/O through EGD and supports dual-backplane operation, redundant-controller outputs and serial service communications.
Base-model capabilities are stated separately from the DN revision identity; no unverified DN-only performance change is inferred.

Functions
Supports the published input and output data capacities and redundant-controller outputs.
Integrates RX3i PCI and Series 90-30 serial-bus modules in the supported station.
Preserves the DN revision for firmware, configuration and spare-control review.
Applications
- Revision-controlled replacement of an installed IC695NIU001-DN.
- Distributed RX3i I/O stations using configured EGD exchanges.
- Remote I/O under redundant PACSystems controllers.
- Maintenance where the exact DN label and configuration archive are available.
Lifecycle
- Export hardware configuration, EGD exchanges, network settings and module map.
- Record the DN label, firmware, power supply, rack and connected serial devices.
- Review Emerson compatibility information before substituting another NIU revision.
- Test I/O, EGD timing, controller switchover, serial paths and restart behavior.
FAQ
Q01What evidence should accompany an IC695NIU001-DN enquiry?
Provide the complete DN label, firmware, rack and power models, configuration-tool version, EGD records, network parameters and quantity.
Q02Can a base IC695NIU001 listing prove compatibility with IC695NIU001-DN?
It confirms the family, not automatic revision interchangeability. The DN suffix, firmware and installed configuration still require review.
Q03How should an IC695NIU001-DN spare be staged?
Load only an approved compatible configuration, preserve a clean rollback copy and document the intended station and network identity.
Q04What should be verified during controller switchover?
Confirm output ownership, safe-state behavior, EGD continuity, diagnostics and process response for every affected I/O group.
Q05What proves IC695NIU001-DN is ready for service?
Confirm DN identity, clean diagnostics, complete I/O results, stable EGD and serial communications, and a passed redundancy test.
About IndustryParts
