4. Product Introduction
The IC697PWR711 is a 100-watt power supply module for the GE Fanuc Series 90-70 PLC system. It installs in the leftmost slot of the rack and accepts a wide-range AC or DC input (90–264 VAC or 100–150 VDC).
It delivers three regulated outputs: +5 VDC (primary logic power), +12 VDC, and –12 VDC. Total output power is limited to 100 W. The supply includes overcurrent and overvoltage protection and provides a minimum 21 ms holdup time. It can also feed a second rack when the combined load remains within the 100 W rating.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No power LEDs / rack dead | No input voltage or blown upstream fuse | ✅ High | Measure input voltage at terminals; check external fuse | Verify source voltage and fusing before replacing PSU |
| +5 V low or missing | Overloaded +5 V rail or failed supply | ✅ High | Measure +5 V on backplane; calculate total 5 V load | Reduce load or replace power supply |
| Overvoltage / shutdown | Internal regulation fault | ✅ High | Check for +5 V rising above 5.7 V | Replace the power supply |
| Intermittent power loss | Marginal input voltage or poor connections | ⚠️ Medium | Monitor input under load; inspect terminal torque | Ensure input stays within specified range |
| Second rack not powered | Total load exceeds 100 W or cable issue | ⚠️ Medium | Calculate combined rack loads; check extension cable | Keep total load ≤ 100 W; verify IC697CBL700 cable |
| Excessive heat / thermal issues | High ambient or blocked airflow | ⚠️ Medium | Check cabinet temperature and ventilation | Improve cooling; derate if necessary |
If input voltage and load calculations are correct and voltages remain out of tolerance, replace the IC697PWR711. Always shut down the system and use proper ESD practices when swapping power supplies.
6. Frequently Asked Questions (FAQ)
Q: What input voltages does the IC697PWR711 accept? A: 90–264 VAC (47–63 Hz) or 100–150 VDC. Nominal ratings are 120/240 VAC or 125 VDC.
Q: What are the output ratings? A: Total 100 W maximum. Typical limits are +5 VDC up to approximately 20 A, +12 VDC up to 2 A, and –12 VDC up to 1 A. The sum of all three outputs must not exceed 100 W.
Q: Can one IC697PWR711 power two racks? A: Yes, using the power supply extension cable (IC697CBL700), provided the combined load of both racks stays within the 100 W rating.
Q: Where does the module install? A: Always in the leftmost slot of a Series 90-70 rack. It plugs directly into the 48-pin backplane connector.
Q: Is the Series 90-70 platform still supported? A: No. The platform is obsolete. Remaining IC697PWR711 units are new surplus or refurbished. Plan migration to current Emerson PACSystems platforms for long-term support.
Q: Why is a new-surplus IC697PWR711 often priced lower than modern power supplies? A: It is an end-of-life Series 90-70 component. New-surplus stock comes from project overstock, is tested, and is sold at a reduced price while still carrying warranty. Condition is clearly stated as New Original / New Surplus.
Q: What is the holdup time? A: Minimum 21 milliseconds from loss of AC input at full load.
