GE Series 90-30 IC693PWR330 120/240VAC 125VDC 30W High Capacity Power Supply

Module Overview

The IC693PWR330 is a high-capacity power supply module engineered for the GE Fanuc Series 90-30 PLC rack. Designed to support larger system configurations, this 30-Watt unit provides the necessary DC voltages to power the CPU, I/O modules, and specialty option cards directly through the backplane. Its universal input stage allows it to operate on standard 120/240 VAC terrestrial power or 125 VDC industrial battery banks, making it a versatile choice for power plants and utility substations.

Detailed Technical Specifications

The IC693PWR330 is built to maintain stable logic-side power even during fluctuations in the primary feed. It includes an integrated battery connection for CPU RAM backup.

Installation and System Integration

The IC693PWR330 occupies the dedicated power supply slot on the far left of any Series 90-30 baseplate. It features a removable terminal block for easy wiring of the incoming AC/DC power and a ground connection. A critical feature of this module is the internal battery port; a lithium battery (IC693ACC301) must be connected here to ensure the CPU retains its program and register data during a complete power loss.

Power Budgeting and Efficiency

When designing a system with the IC693PWR330, engineers must ensure the cumulative current draw of all modules in the rack does not exceed the 30-Watt threshold. This "High Capacity" version is specifically intended for racks containing several high-draw modules, such as Ethernet Co-Processors or high-density analog cards, which would otherwise exceed the limits of standard 15W or 20W power supplies.

Technical FAQ

Can I use the 24VDC output on this module to power external field sensors?

The "Isolated 24VDC" output is primarily intended to provide power to specific 90-30 I/O modules. While it can technically power small external loads, exceeding the 20-Watt limit on this rail will cause the power supply to shut down or fail prematurely.

What is the difference between the IC693PWR330 and the IC693PWR321?

The IC693PWR330 is a "High Capacity" unit providing 30 Watts of total power, whereas the PWR321 is a standard unit typically rated for lower wattage. The PWR330 is the preferred replacement when adding more I/O modules to an existing rack that is experiencing intermittent power resets.

Does this module support 24VDC input?

No. The IC693PWR330 requires a high-voltage input (120/240VAC or 125VDC). For 24VDC input applications, the IC693PWR322 or IC693PWR331 should be used instead.
