Product Introduction
The GE IC693PWR330 is a robust power supply designed for the Series 90-30 PLC architecture, accepting standard global AC voltages (120V or 240V) without manual jumper settings. It delivers stable 5V DC logic power to the backplane and a dedicated 24V DC rail for powering communication modules or limited field devices.Distinguished from lower-wattage models like the PWR321 (30W), the IC693PWR330 provides up to 8A on the 5V rail, making it suitable for racks populated with multiple high-current specialty modules (e.g., motion control, high-density I/O). Its auto-ranging input simplifies deployment in facilities with fluctuating line voltages or international exports.
Installation & Configuration Guide
Phase 1: Preparation (10 min)
Lock out all AC power sources. Verify the incoming voltage is within the 120–240V AC range. Inspect the terminal block for damaged screws or signs of arcing. Ensure the rack has adequate ventilation; this unit dissipates ~10W of heat at full load. Note that no voltage selection jumpers are required; the unit detects input automatically.Phase 2: Removal (5–10 min)
Disconnect the AC wiring from the front terminal block (Line, Neutral, Ground). Label wires clearly. Loosen the captive mounting screws at the top and bottom of the module faceplate. Use the ejector handles to pull the module straight out. Avoid twisting the module, as this can damage the backplane power pins.Phase 3: Installation (10 min)
Slide the new IC693PWR330 into any available slot in the Series 90-30 rack (power distribution is parallel across the backplane). Push firmly until seated. Tighten captive screws to 4.5 in-lbs. Reconnect AC wiring: Line (L), Neutral (N), and Chassis Ground (G). Critical: Ensure the ground connection is solid; poor grounding causes noise issues in analog modules. Torque terminal screws to 5–7 in-lbs. Loose AC terminals are a primary cause of fire hazards in older panels.Phase 4: Power-On & Test (10 min)
Remove LOTO and energize the AC source. Observe the front LEDs: PWR (Green) should illuminate immediately. The OK LED will flash then go solid green if internal self-tests pass. Measure the 5V output at a known good point on the backplane (or via a diagnostic module if available); it should read 5.0V ±2%. If the PWR LED is off, check the input fuse and AC continuity. If OK flashes red, the backplane load may exceed 50W.
Troubleshooting Quick Reference
| Symptom | Probability | Action |
|---|---|---|
| PWR LED Off | High | No input voltage or blown internal fuse. Measure AC at terminals. Check external breaker. |
| OK LED Flashing Red | Medium | Overload condition. Calculate total backplane current draw. Remove non-essential modules to test. |
| 24V Output Low (<22V) | Medium | Excessive load on 24V rail. This supply only provides 1.0A @ 24V. Use an external 24V supply for field devices/sensors. |
| Module Hot to Touch | Low | Ambient temperature >60°C or blocked airflow. Thermal shutdown occurs at ~85°C internal. Clean rack filters. |
| Intermittent Reset | Low | AC line noise or brownouts. Check for large motor starts on the same circuit. Add line reactor if necessary. |
Dimensions, Mounting & Wiring Notes
- Dimensions: 1.60″ W × 6.50″ H × 5.90″ D (Single Horizontal Slot)
- Mounting Method: Slides into Series 90-30 universal backplane; secured by two captive front-panel screws.
- Terminal Notes:
- Input: Screw terminals for Line (L), Neutral (N), and Chassis Ground (G). Wire gauge: 14–22 AWG.
- Output: Internal distribution via backplane. No external output terminals for 5V.
- 24V Aux: Available for limited internal use. Do not rely on this for powering a full rack of 24V sensors; capacity is only 1A.
- Torque: Critical. Loose AC terminals cause heat buildup and melting plastic. Retorque after 24h of operation if possible.

FAQ
Q: Can I use the IC693PWR330 in a Series 90-70 rack?
No. The physical form factor and backplane pinout are different. The Series 90-70 uses larger IC697PWR series modules. Forcing this module into a 90-70 rack will bend pins and likely short the backplane.Q: My system needs 12A @ 5V. Will two PWR330 modules work together?
No, you cannot parallel these power supplies for increased current. The Series 90-30 backplane does not support active load sharing between multiple power supplies. You would need to split the I/O across two separate racks, each with its own power supply.Q: Does this unit require a voltage selector switch for 240V?
No. The IC693PWR330 features auto-ranging input circuitry. It automatically detects whether 120V or 240V is applied and adjusts internally. Just wire it up and power it on.Q: Is the 24V output enough to power my sensors?
Unlikely for a full rack. The IC693PWR330 only provides 1.0A @ 24V, intended mostly for powering communication modules or a few low-current sensors. Best practice is to use an external 24V DC power supply for the majority of field instrumentation and wire them separately.Q: How do I know if the unit is refurbished or new surplus?
Check the date code on the serial number label. If the date is >10 years old, it is surplus stock. If the label looks fresh or has a “Tested” sticker from a third party, it is refurbished. We always disclose this status in the product condition field. Never assume “New” means factory sealed for discontinued items.
