4. Product Introduction
The GE IC695PSD040 is a 40-watt DC power supply for the PACSystems RX3i universal backplanes. It converts 24 VDC input into the regulated voltages required by the backplane and installed modules.
This power supply supports both single and redundant configurations in RX3i racks. It is a standard choice for systems needing reliable 24 VDC sourced power in industrial environments.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No output / power LEDs off | No input voltage | ✅ High | Measure 18-30 VDC at input terminals | Verify upstream 24 VDC supply |
| Overload LED on | Excessive rack current draw | ✅ High | Calculate total module consumption | Reduce load or add redundant supply |
| Intermittent power | Loose input wiring | ✅ High | Inspect and tighten terminal connections | Secure all power wiring |
| Low output voltage | Input voltage below minimum | ✅ Medium | Monitor input voltage under load | Correct input supply voltage |
| Relay output not working | External circuit issue | ❌ Low | Test relay contacts with multimeter | Check external 24 VDC wiring |
Contact technical support with input/output voltage measurements and rack load details if problems persist.
6. Frequently Asked Questions (FAQ)
What input voltage does the IC695PSD040 require? It accepts 18–30 VDC, with nominal operation at 24 VDC. Do not exceed these limits.
Can I run redundant power supplies with this model? Yes. You can install two IC695PSD040 units in the same rack for redundancy. The system automatically shares the load.
How much total power is available? The module delivers up to 40 watts across its outputs. Always calculate the combined backplane consumption of all installed modules before finalizing your design.
Is this power supply hot-swappable? Yes, in redundant configurations when proper procedures are followed. For single-supply systems, power down the rack first.
Does it provide 24 VDC for field devices? It has a limited +24 VDC relay output for control purposes. Use a separate field power supply for I/O loads.
Why choose New Surplus for this power supply? These units are genuine OEM stock that passed factory testing and were never installed. They offer immediate availability and cost savings compared to new production units.
What should I check before installing a replacement? Confirm total rack power requirements stay within 40W and verify input voltage is stable within 18–30 VDC. Take photos of the existing wiring before removal.
