GE IC695PSA040 Power Supply | Replacement, Equivalent & Selection Guide
The GE IC695PSA040 is a 40-Watt AC power supply module designed for the GE PACSystems RX3i programmable logic controller (PLC) platform. It provides regulated DC power to the RX3i backplane, supporting CPU modules, I/O modules, and communication cards within the same rack system.
Selection Background
Industrial buyers searching for an IC695PSA040 replacement or IC695PSA040 equivalent typically face one of three scenarios: an end-of-life procurement challenge, a cost-optimization review, or an emergency repair situation. Understanding which substitute models are direct drop-in replacements versus functional equivalents—and which cross-brand alternatives require engineering validation—is critical to maintaining system uptime and safety compliance. This guide is designed to help you make that determination quickly and confidently.

Compatible Replacement & Equivalent Models
1. Direct Drop-in Replacements
The following models are mechanically and electrically interchangeable with the IC695PSA040 and require no configuration changes:
- IC695PSA040-ABAJ — Revision variant; functionally identical, same firmware baseline.
- IC695PSA040E — Enhanced revision released by GE; backward-compatible with all RX3i backplanes.
Prerequisite: Confirm backplane model is IC695CHS012 or IC695CHS016. No wiring or slot changes required.
2. Functional Equivalents
These models provide equivalent power output within the RX3i platform but may differ in input range or form factor:
- IC695PSA140 — 40 W AC supply, extended temperature rating (−20 °C to 60 °C); suitable substitute where environmental specs allow.
- IC695PSD040 — 40 W DC input variant (18–30 VDC); use only when AC input is unavailable. Note: Input wiring must be changed.
Prerequisite: Verify input power type (AC vs. DC) and rack slot availability before substituting.
3. Cross-Brand Alternatives
These third-party or alternative-platform power supplies may serve as engineering substitutes in non-safety-critical applications:
- Emerson / Vertiv equivalents — Post-GE acquisition rebranded units; verify part number mapping via Emerson cross-reference tool.
- Phoenix Contact QUINT series — External DIN-rail PSU; requires external power conditioning and backplane adapter. Engineering review mandatory.
Note: Cross-brand alternatives are not plug-and-play. Always perform full compatibility validation before deployment in production environments.
Why Choose the Original Model
- Precision Power Delivery: Factory-calibrated output voltages ensure stable backplane operation across all RX3i module types.

- Water & Wastewater: Pump station control cabinets with 24/7 continuous duty cycles.
- Power Generation: Turbine governor and auxiliary control panels in combined-cycle power plants.
- Food & Beverage: Packaging line PLCs operating in washdown-adjacent environments (IP20 cabinet-mounted).
- Building Automation: Central HVAC and BMS controllers integrated with GE PACSystems infrastructure.
System Compatibility
- IC695CHS012 — 12-slot RX3i universal backplane (primary host rack)
- IC695CHS016 — 16-slot RX3i universal backplane (expanded host rack)
- IC695CPU310 / IC695CPU315 / IC695CPU320 — RX3i CPU modules powered by this supply
- IC695ETM001 — Ethernet interface module (rack-powered)
- IC695PBM300 — PROFIBUS master module (rack-powered)
- IC694MDL754 / IC694MDL655 — Digital I/O modules (via expansion backplane)
Selection Guide
Answer these three questions before confirming your order or selecting a substitute:
- What is your backplane model? — Only IC695CHS012 and IC695CHS016 are compatible. If you are using an IC694 (Series 90-30) backplane, you need a different power supply family.
- What is your available input power? — The IC695PSA040 requires 85–264 VAC. If your panel provides only DC power, consider the IC695PSD040 instead.
- What is your total rack power budget? — Sum the power consumption of all installed modules. If it exceeds 40 W, you may need the IC695PSA140 or a dual-supply configuration.

Replacement & Compatibility FAQ
Q: Can the IC695PSA040E replace the IC695PSA040 directly?
A: Yes. The IC695PSA040E is a direct drop-in replacement for the IC695PSA040. It is backward-compatible with all IC695 series backplanes and requires no configuration changes.
Q: Is the IC695PSD040 a compatible equivalent to the IC695PSA040?
A: The IC695PSD040 is a functional equivalent in terms of output power (40 W) and backplane interface, but it accepts DC input (18–30 VDC) rather than AC. It is not a plug-and-play substitute unless your panel already provides a suitable DC source.
Q: Can a third-party DIN-rail power supply substitute for the IC695PSA040?
A: Third-party external supplies can serve as cross-brand alternatives in non-safety-critical applications, but they require an external backplane power adapter and full engineering validation. Konmask does not recommend this approach for production systems without prior testing. Contact us for a validated alternative recommendation.
