GE Fanuc IC693PWR331 30W PLC Logic Power Supply

Product Overview

The GE Fanuc IC693PWR331 is a high-capacity power supply module specifically engineered to support advanced CPU modules and dense I/O configurations within the Series 90-30 programmable logic controller (PLC) platform. Operating from a nominal 12 VDC input voltage source, this robust module delivers highly regulated 5 VDC logic power alongside dual isolated and relay 24 VDC outputs. Weighing 0.6 kg (1.32 lbs), its compact and efficient design ensures stable, low-noise power distribution required for sensitive industrial automation and control environments.

Core Technical Advantages

• High-Capacity Logic Delivery: Supplies up to a full 3 Amps at 5 VDC directly to the backplane, ensuring stable processing for power-intensive CPUs and multi-channel communication modules.
• Dual-Track 24 VDC Isolation: Features separate 24 VDC relay (0.62 A) and isolated (0.83 A) outputs, providing essential electrical separation to shield internal backplane logic from external field instrumentation noise.
• Certified Industrial Compliance: Built to rigorous global standards, the module carries full UL and CE certifications, guaranteeing high operational reliability and safety under full-load industrial configurations.

Technical Specifications

Installation & Engineering Guide

• Backplane Placement: Prior to mounting, verify that the 12 VDC input supply line is completely de-energized. Slide the 0.6 kg module firmly into the leftmost slot of the Series 90-30 baseplate until the rear connectors click into position, ensuring optimal interface connection with the backplane bus.
• Terminal Block Wiring: Secure the 12 VDC input lines using the 3 robust front-panel terminal screws. Ensure tight terminal connections and clear routing of wires away from neighboring communication lines to prevent electromagnetic cross-talk.
• System Power Budgeting: While the individual output tracks can supply significant localized power (30W for 5V CPU, 15W for Relay, and 20W for Isolated), the combined simultaneous load distributed across all three voltage paths must not exceed the absolute 30 Watts total output threshold.

Technical FAQs

Q1: What is the primary difference between the 24 VDC Isolated and 24 VDC Relay outputs?
A1: The isolated output provides a clean, independent 24 VDC source to power external input modules and field sensors safely, whereas the relay output track is dedicated strictly to supplying circuit power for external output relay coils.

Q2: Why does the unit list both a 30W total output power and a 50W full load power rating?
A2: The 30 Watts represents the maximum total power available for downstream modules via the backplane, while the 50 Watts specification includes internal power conversion dissipation and heat overhead when running at maximum capacity.

Q3: Can this module operate directly on standard 24 VDC battery banks or power grids?
A3: No. The IC693PWR331 is designed strictly for a nominal 12 VDC input source. Connecting this unit directly to a 24 VDC supply line will cause irreversible overvoltage damage to the internal power conversion circuitry.
