GE Fanuc IC694PWR330 RX3i Power Supply

IC694PWR330 GE Fanuc RX3i Power Supply Module

Product Introduction

The IC694PWR330 from GE Fanuc is a robust serial expansion power supply designed specifically for the RX3i PacSystems platform. This module provides reliable auxiliary power to programmable logic controllers in demanding industrial environments.

Its wide-range input accepts both AC and DC voltages, offering great flexibility for global installations. Moreover, the IC694PWR330 delivers clean, regulated DC outputs to support additional I/O and specialty modules.

Because it is a serial expansion device, you must install it in the dedicated serial expansion backplane. Never attempt to hot-swap this unit. Always disconnect system power before installation or removal to ensure safety and protect sensitive components.

Key Technical Specifications

The IC694PWR330 handles a broad range of input sources. For AC operation, the acceptable range spans from 85 to 264 volts AC. For DC systems, it accepts 100 to 300 volts DC. These wide tolerances make it suitable for unstable mains or battery-backed supplies.

This module provides three isolated output rails. Specifically, it supports 30 watts at 5 volts DC, 20 watts at 24 volts DC isolated, and 15 watts at 24 volts DC relay voltage. The total combined output capacity is sufficient for most expansion racks.

Furthermore, the unit draws a nominal current of 2 amps. It uses a dedicated GE 44A724627-109 fuse for reliable overcurrent protection. This fuse type is standard and easily replaceable if needed.

The terminal block accepts wire sizes up to 12 AWG. The recommended tightening torque for connections is 12 pound-inches, which equals 1.3 N-m. Proper torque ensures stable electrical contacts and prevents overheating.

Mechanical and Environmental Parameters

Physically, the IC694PWR330 follows the standard RX3i module form factor. It mounts directly onto the serial expansion backplane using built-in retaining clips. The module occupies one slot in the rack.

For cooling, the unit relies on natural convection. Therefore, you must maintain adequate clearance around the heat sink fins. The operating temperature range is 0 to 60 degrees Celsius. Storage temperature can be from -40 to 85 degrees Celsius.

Relative humidity should stay between 5% and 95%, non-condensing. These environmental ratings match typical factory floor conditions. Additionally, the module meets UL and CE standards for industrial control equipment.

Installation Guidelines for the IC694PWR330

Before mounting the IC694PWR330, set the rack number selection DIP switch on the backplane correctly. This step is critical because the CPU uses this address to identify each expansion rack.

Next, align the module with the upper and lower card guides on the backplane. Slide it firmly into place until the connectors mate securely. Then, tighten the two retaining screws to the specified torque of 12 pound-inches.

After mechanical installation, connect the input power wires to the terminal block. Observe correct polarity for DC wiring. For AC wiring, both line and neutral are symmetrical. However, always verify local electrical codes before energizing.

Finally, apply power and check the front-panel LED indicators. A steady green light confirms normal operation. If the LED is off or red, recheck the input voltage and fuse condition.

Important Operational Notes

The IC694PWR330 does not support load-sharing redundancy. This means you cannot parallel two units for increased capacity or fault tolerance. If your application requires high availability, consider using a separate redundant power architecture.

Nevertheless, this module performs excellently as a dedicated expansion supply. It works seamlessly with any RX3i CPU, from the base model to the high-performance options. Therefore, it is a versatile choice for system upgrades or new builds.

Remember that this unit only provides power to the expansion backplane. It does not communicate data or affect the CPU's logic execution. Its sole purpose is to supply stable voltage to the modules in that specific rack.

Packaging and Delivery Information

Each new IC694PWR330 unit ships in a factory-sealed anti-static bag. The retail box includes the module itself, a set of two retaining screws, and a quick-start guide. For your convenience, the terminal block connector is pre-installed on the module.

The package does not include any mounting backplane, wiring cables, or external fuse holders. Those items must be ordered separately based on your system layout. Also, no software or configuration tool is provided with this hardware item.

All shipments are insured and tracked. We use major global couriers including FedEx, UPS, and DHL. Delivery times vary by destination, but most in-stock orders dispatch within 24 hours of payment confirmation.

Frequently Asked Questions

1. Can I use the IC694PWR330 with a 480V AC supply?
No. The maximum AC input is 264 volts. For 480V systems, you must use a step-down transformer before connecting to this module.

2. How do I check if the IC694PWR330 is working properly?
Observe the front LED. A steady green light means normal output. No light indicates missing input or a blown internal fuse. Red light signals an overcurrent or short-circuit condition.

3. Is this module compatible with the older Series 90-30 backplane?
No. The IC694PWR330 is designed exclusively for the RX3i serial expansion backplane. It will not physically fit or electrically mate with Series 90-30 racks.

4. What happens if I install the IC694PWR330 while the system is powered?
Hot-plugging is strictly prohibited. Doing so may cause arcing, damage the module, the backplane, or adjacent cards, and could result in personal injury. Always power down the entire rack first.

5. Can I replace the internal fuse myself?
Yes. The fuse type is GE 44A724627-109. After removing input power, open the fuse holder on the front panel and replace it with an identical rating. Do not use a higher-amperage substitute.
