Product Overview

The IC693PWR331 is a high-capacity power supply module for the GE Fanuc / Emerson Series 90-30 PLC system. This 100% brand new, original unit converts 120/240 VAC or 125 VDC input into regulated DC outputs required by the CPU, I/O modules, and field-side circuits. Designed for higher-demand configurations, it provides stable multi-rail power distribution for racks using analog, relay, and communication modules.

Technical Specifications

Engineering Advantages

Optimized Power Allocation
Flexible power distribution allows the full 30 W capacity to be directed to the +5 V logic rail when required, supporting CPU-heavy and memory-intensive configurations.

Dual +24 VDC Output Design
Separate Relay and Isolated 24 V outputs reduce electrical noise and ground loop issues while supporting both output module coils and field input circuits.

Universal Input Capability
Supports 120/240 VAC and 125 VDC inputs, enabling global deployment without additional transformers or converters.

System-Level Protection
Integrated over-voltage and over-current protection ensures safe shutdown under fault conditions, protecting CPU and I/O modules from electrical damage.

FAQs

What is the difference between +24 V Relay and +24 V Isolated outputs?
The Relay output powers internal relay module circuitry, while the Isolated output provides clean, electrically separated power for input modules and field devices.

Is the 30 W rating per output?
No. The 30 W rating is the total combined output across all rails.

Can it replace the IC693PWR321?
Yes. It is a higher-capacity, direct-fit replacement for the IC693PWR321 with identical physical mounting and enhanced power capability.

Where is the system battery installed?
The IC693ACC301 lithium battery is installed behind the front access panel of the power supply and maintains RAM and real-time clock during power loss.
