Backplane Bus Communication Velocity & Firmware Flash Compatibility
The IC695NIU001-CK interfaces directly with the RX3i Universal Backplane, delivering optimized backplane bus communication velocity and minimal I/O transfer latency. Internal energy-storage capacitors ensure hold-up time to preserve network connectivity during brief electrical interruptions. High-speed dual RJ45 interfaces allow deterministic network traffic handling for up to 64 remote I/O modules. Strict firmware flash compatibility across backplane revisions ensures synchronized data exchange without signal degradation or packet loss.
Frequently Asked Questions
Q: What function do the internal energy-storage capacitors serve on the IC695NIU001-CK?
A: The internal capacitors provide temporary electrical hold-up time during momentary power fluctuations, maintaining active Ethernet link connections and preserving network state during brief supply interruptions.
Q: How is system time maintained on the IC695NIU001-CK when main input power is completely removed?
A: An internal real-time clock backed up by a replaceable lithium battery retains date and time parameters during total system power outages.
Field Installation Guidelines
Always isolate the main supply power to the chassis prior to installing or removing the IC695NIU001-CK from the RX3i Universal Backplane. Confirm that the module is correctly aligned in its backplane slot and fully seated to secure backplane power connection and chassis ground grounding. Both Ethernet cables must be category-rated, shielded twisted-pair cables, and field cable shields must be grounded in accordance with standard industrial network wiring guidelines to mitigate electro-magnetic interference.
