IC693PWR328 GE Fanuc 30W PLC Power Supply

Product Overview

The GE Fanuc IC693PWR328 is a high-efficiency, 30 Watt max output power supply module designed specifically for the Series 90-30 programmable logic controller (PLC) platform. Operating from a nominal 48 VDC input voltage source, this rugged module delivers highly regulated 5 VDC power to the local CPU alongside dual isolated and relay 24 VDC outputs. Weighing approximately 0.52 kg (1.15 lbs), this module occupies the leftmost slot of any standard Series 90-30 baseplate, serving as the stable electrical cornerstone for complex factory automation systems.

Core Technical Advantages

• Multiple Isolated DC Outputs: Distributes independent 5 VDC and 24 VDC voltage rails to enable safe component separation, completely eliminating the risk of cross-module electrical damage.
• Integrated RS-485 Serial Interface: Features a built-in RS-485 communication port that facilitates direct, high-speed connections to local programming PCs, operator interface terminals, or diagnostic tools.
• Comprehensive Health Tracking: Equipped with 4 vivid front-panel LED status indicators that provide real-time hardware diagnostics, drastically simplifying field troubleshooting and fault detection.

Technical Specifications

Installation & Engineering Guide

• Backplane Positioning: Ensure primary power feeds are completely isolated before installation. Always slide the 0.52 kg hardware frame into the leftmost slot position on the Series 90-30 baseplate, pushing backward firmly until the alignment pins snap the module connectors tightly to the backplane grid.
• Battery Integration: Unlatch the front maintenance access panel and seat a fresh Lithium backup battery into the integrated compartment before running power. This initialization secures application logic states and prevents complete data loss across the CPU memory circuits during standard plant brownout conditions.
• Output Power Budgeting: Calculate the aggregate power draw of your system modules prior to startup. Individual output tracks can handle up to 15 Watts (5V CPU / 24V Relay) and 20 Watts (24V Isolated), but the combined simultaneous power draw across all three rails must not exceed the absolute 30 Watts total output limit.

Technical FAQs

Q1: What problem does the isolated 24 VDC output loop solve for my field equipment?
A1: The isolated 24 VDC output circuit separates field instrumentation noise and ground loop potentials from the sensitive digital logic backplane, protecting internal PLC components against unexpected voltage spikes and external wiring failures.

Q2: Can the integrated RS-485 serial interface be used for continuous process monitoring?
A2: Yes. The onboard RS-485 port is fully optimized to maintain robust, continuous serial communications with local operator interfaces, host computers, or multi-drop diagnostic networks running standard automation protocols.

Q3: How does the module indicate internal circuit health and input power availability?
A3: The faceplate features a bank of 4 distinct diagnostic LED status indicators. These lamps illuminate in specific patterns to display real-time statuses regarding input line power availability, internal logic faults, and overall output rail functionality.
