When a Controller Loses Power, Memory Must Not Follow
A plant engineer watches a PACSystems RX3i rack go dark during a scheduled breaker test. The logic, setpoints and accumulated data all depend on one small accessory staying connected. That accessory is the IC695ACC400-AA, a battery backup kit built for the GE Fanuc PACSystems RX3i platform and now owned by Emerson.
The kit protects controller memory when main power drops. It connects through a dedicated cable and mounts directly on the left side of the module in rack slot 0, so it stays inside the rack envelope instead of hanging loose in the cabinet.
What Ships in the IC695ACC400-AA Kit
The IC695ACC400-AA is a battery backup accessory, not a standalone controller. Its job is simple: hold memory contents during outages and short power interruptions. The kit uses the IC695CBL001 cable, available in 0.91 m or 3 m lengths, and terminates with a Samtec PID1-040D-K connector. That connector mates with the RX3i module’s battery port.
Mounting is fixed: left side of the module, rack slot 0. This placement keeps the cable run short and reduces strain on the connector. For engineers replacing a failed or missing backup assembly, matching the correct cable length to the cabinet layout matters more than most people expect.

Why This Kit Matters on the Plant Floor
RX3i controllers run logic that often cannot be recreated quickly. A battery backup kit keeps that logic intact through brownouts, breaker tests and generator transfers. In oil and gas terminals, where restart sequences can take hours, the IC695ACC400-AA protects against avoidable downtime.
Water treatment plants use the same logic. A short outage during a pump cycle should not wipe the program. The IC695ACC400-AA keeps the controller’s memory alive so operations resume without a full reload.
Fitting the Kit Correctly
Installation follows the rack layout. The battery backup mounts on the left side of the module in slot 0. Route the IC695CBL001 cable away from high-voltage wiring where possible. Confirm the Samtec PID1-040D-K connector seats fully before closing the panel.
Before ordering, verify the cable length you need. The 0.91 m option suits compact racks; the 3 m option reaches across larger enclosures. If you are unsure which length fits your cabinet, the team at Oil AutoTech can help match the right configuration.
Sourcing and Availability
Emerson’s official production status for this kit is unverified. Units remain available through aftermarket channels, with last verification in September 2026. That means buyers should confirm current stock before committing to a project schedule.
