4. Product Introduction
The GE Fanuc IC698PSA100C is a universal power supply for PACSystems RX7i racks. It slides into the dedicated leftmost slot and delivers regulated +5 V, +12 V, and –12 V to the backplane, powering the CPU, I/O modules, and intelligent devices in demanding applications like turbine control, large presses, or redundant process systems.
This supply handles wide AC/DC inputs with power factor correction, making it flexible for global installations. RX7i users rely on it for reliable hold-up during brief outages and diagnostic LEDs that flag field/ output status or overtemperature quickly—keeping downtime low in legacy high-performance setups where full migration isn’t justified yet.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No LEDs lit (no FIELD OK) | No input power or fuse blown | ✅ High | Measure input terminals (85–264 VAC or 100–150 VDC) with multimeter | Verify upstream breaker/fuse; check input wiring |
| OUTPUT OK LED off | Overload, short, or internal fault | ✅ High | Measure +5 V at backplane test points; check total load <100 W | Reduce rack load; reseat or replace PSU |
| OVER TEMP LED on | High ambient or blocked vents | ✅ High | Check rack temp (0–60 °C); feel for hot spots | Improve ventilation; add fans if needed |
| Intermittent power drops | Marginal input voltage or hold-up fail | ✅ Medium | Monitor input during brownout; scope hold-up time | Stabilize input supply; test with known good unit |
| +5 V output low/under 4.875 V | Overcurrent or aging caps | ✅ High | Measure +5 V rails under load | Check total consumption; replace PSU if persistent |
| No power to rack after swap | Wrong slot or poor insertion | ✅ High | Confirm slot 0 only; reseat firmly | Power cycle rack; verify seating |
| Fan noise or overheating | Dust buildup or failed fan | ❌ Low | Inspect vents/fan; clean if dirty | Clean or replace if fan seized |
RX7i power issues almost always trace to input feed, overload, or rack environment—not the PSU failing randomly. Measure actual input voltage and total backplane draw first. Snap photos of LEDs and multimeter readings; send them if it’s flaky—we can rule out quick.

6. Frequently Asked Questions (FAQ)
What’s the -C suffix on IC698PSA100C? It’s a revision indicator (like -A, -B, -C variants). No changes to input ranges, output ratings, or compatibility from base IC698PSA100. We’ve swapped C revisions into live RX7i racks without issues or reconfig.
Is the IC698PSA100C still produced new by Emerson? No, RX7i power supplies are obsolete. We stock new surplus—unused, sealed or new-old-stock from decommissioned spares. They deliver full 100 W output like day-one units but without active OEM warranty.
Can this PSU handle redundant setups? No native redundancy in one unit. For high-availability RX7i racks, pair two PSUs in compatible configurations (check manual for parallel wiring if supported). This model is single-supply primary.
How do I calculate if my rack load fits? Sum module power draws from datasheets (most CPUs/I/O list mA at +5 V, +12 V, –12 V). Keep total under 100 W combined. Leave 20% headroom for spikes. Over 100 W trips protection and drops OUTPUT OK.
Will swapping the PSU cause rack downtime? Power down first—RX7i isn’t hot-swap for power supplies. Swap takes minutes; config and programs stay in CPU (battery-backed). Power up and verify LEDs.
Why surplus over refurbished PSUs? Surplus units have no runtime hours—no capacitor aging or thermal stress. Refurbs often come from overloaded failures and get minimal recaps. We test every IC698PSA100C: input sweep, full-load output check (+5 V at 15–20 A sim), LED verification, and 24-hour run.
What warranty do you offer? 1-year functional when installed per specs. Covers defects, not overload, input surges, or poor ventilation. Test reports with voltage readings and load test data available on request.
