IC693PWR331 GE Fanuc Series 90-30 High Capacity Power Supply

Product Overview

The IC693PWR331 is a 30-watt, wide-range DC input High Capacity power supply specifically designed for the GE Fanuc Series 90-30 PLC. It operates on a 24 VDC nominal input and is engineered for applications requiring higher +5 VDC current capacity than standard supplies, allowing the full 30-watt output to be consumed by the +5 VDC rail. This module is a "High Capacity" version, meaning it provides robust power distribution for demanding processor and I/O configurations within a single rack.

Technical Configuration

The IC693PWR331 features a flexible hardware architecture to support various Series 90-30 system requirements:

• Input Voltage Range: Accepts 12 to 30 VDC for continuous operation. Minimum startup voltage is 18 VDC.
• Triple Output Logic: Provides +5 VDC for backplane logic, +24 VDC relay power, and isolated +24 VDC output for external circuits.
• Serial Communication: Includes integrated RS-485 compatible serial port for programmer or operator interface connection.
• System Diagnostics: Four LED indicators: PWR, OK, RUN, and BATT for power and system status monitoring.
• Battery Support: Provides connector for lithium backup battery to maintain CMOS memory and real-time clock.

Technical Specifications

Technical FAQs

Can I use the full 30 watts just for the PLC rack modules?
Yes. For applications requiring significant +5 V current, the supply allows the full 30 W to be drawn from the +5 VDC output if other rails are lightly loaded.

What happens if the isolated 24 VDC output is shorted?
If the isolated +24 VDC output is overloaded or shorted, the controller stops operation to protect the system.

Why will the power supply not start at 15 VDC?
The unit can operate down to 12 VDC after startup, but requires at least 18 VDC during initial power-up.

Engineering & Installation Guide

• Field Wiring Input: Connect DC input to the top three terminals. Top terminal is positive, second terminal is negative, third terminal is ground.
• External Power Output: Bottom terminals provide isolated +24 VDC output. Total load must remain within the 30 W limit.
• Thermal Management: Above 50 deg C ambient temperature, reduce +5 VDC output load to maintain stable operation.
• Input Power Calculation: Multiply total output power by 1.5, then divide by input voltage. Add 10 to 20 percent margin.
