Product Overview
Downtime on a PACSystems RX3i rack rarely waits for a purchase order. The IC695PSA040J is a 40 W AC input power supply module built for RX3i backplanes, originally from GE Fanuc / GE Intelligent Platforms and now under Emerson ownership. It converts a wide AC input into the three DC rails an RX3i rack needs to keep I/O and control modules running.
This is a practical spares item, not a shelf ornament. If your line runs on RX3i hardware, this module is the kind of part you want identified and ready before a failure stops production.

What the Wide Input Range Means for You
The 85-264 V AC input at 47-63 Hz covers low and high line conditions without a selector switch. In plants where supply voltage drifts, that headroom protects the rack from nuisance trips. The 40 W output budget is modest by design, so match it to your actual module count before ordering.
Where This Module Fits
RX3i racks appear across oil and gas, water treatment, and general process automation. Three common situations:
- Legacy panel rebuilds. An existing RX3i rack needs a replacement supply without a full platform migration.
- Remote wellsite cabinets. Wide AC input tolerates generator-fed or unstable supply conditions.
- Spares stocking. One spare module on the shelf can cut a multi-day outage to a same-day fix.
Integration Notes
The IC695PSA040J slots into an RX3i backplane and feeds the rack rails. Because it is a backplane supply rather than a fieldbus device, no network gateway is involved. Confirm your rack model, slot position, and total load before installation, and follow the manufacturer’s installation manual for mounting and torque values.
Buying Checklist
Before you commit, verify these points:
- Rack compatibility — confirm the module is intended for your RX3i chassis and slot.
- Load budget — total the current draw of installed modules against the 40 W output and 6 A per-terminal limit.
- Environment — the 0 to +60°C ambient rating and IP20 protection suit clean cabinet installations, not washdown areas.
- Lifecycle status — official Emerson production status is unverified; the part is currently available in aftermarket channels (last verified 2026-09).
Please verify current lifecycle status and availability with Oil AutoTech before ordering. For hands-on technical selection help, contact Oil AutoTech today for pricing and availability.
