I/O modules

Product Overview

The GE IC693PWR330 functions as a high-capacity power supply module for the GE Fanuc Series 90-30 programmable logic controller platform. This unit provides reliable DC power to the CPU, I/O modules, and optional equipment in industrial control systems. We engineered the IC693PWR330 to deliver clean, regulated power for demanding automation applications worldwide.

Technical Specifications

Key Features and Benefits

• Triple Output Capability: The IC693PWR330 provides three independent DC outputs from a single power supply. You therefore power logic circuits, relay outputs, and isolated field devices without additional supplies.

• Universal AC/DC Input: This module accepts both AC and DC input voltages over a wide range. Consequently, you use the same power supply in facilities worldwide without modification.

• High Output Capacity: With 30 watts total power, this supply supports larger Series 90-30 configurations. You populate more I/O modules in the rack while maintaining reliable operation.

• 20 ms Holdup Time: The supply maintains output during brief AC power interruptions. Therefore, the PLC continues operating through momentary dips and transfers.

• Comprehensive Protection: Built-in overvoltage and overcurrent protection safeguards both the supply and connected modules. Automatic recovery minimizes downtime after fault conditions clear.

Detailed Functional Description

The primary function of the GE IC693PWR330 involves converting incoming AC line power or DC source power into the regulated voltages required by Series 90-30 modules. Specifically, it mounts in the leftmost slot of the rack and distributes power through the backplane connectors. The +5 VDC output powers all module logic circuits and the CPU. The +24 VDC relay output provides power for internal relay coils within output modules. The isolated +24 VDC output supplies power for field devices such as sensors and pushbuttons. The module includes filtering and regulation to ensure clean, stable power for reliable PLC operation.

Output Specifications and Loading

We designed the IC693PWR330 with three distinct outputs for different load requirements:

The total load across all outputs cannot exceed 30 watts maximum combined.

Input Power Characteristics

The GE IC693PWR330 accommodates worldwide power inputs:

• AC Operation: 85-264 VAC, 47-63 Hz, 90 VA maximum input

• DC Operation: 100-300 VDC, 50 W maximum input

• Inrush Current: Limited to 4A peak for 250 ms

• Hold-up Time: 20 ms minimum at nominal voltage and full load

• Efficiency: >75% typical at full load

Protection Features

The IC693PWR330 incorporates multiple protective functions:

• Overvoltage Protection: Crowbar protection on +5 V output activates at approximately 6.2 V

• Overcurrent Protection: Electronic current limiting with automatic recovery on all outputs

• Short Circuit Protection: Continuous protection with no damage to the supply

• Overtemperature Protection: Thermal shutdown with automatic reset

• Input Transient Protection: Internal varistors and filters suppress line surges

Installation and Configuration

Engineers install the IC693PWR330 in the dedicated power supply slot of a Series 90-30 rack. The process involves:

1. Ensuring the rack is properly mounted and grounded

2. Inserting the module into the leftmost slot until it latches securely

3. Connecting AC or DC power to the 6-position terminal block

4. Applying power and verifying the green LED illuminates

5. Checking that all rack modules receive power

The module requires no configuration; it automatically provides power when installed.

Communication and Monitoring

The IC693PWR330 includes an RS-485 communication port for power supply monitoring. You connect this to the CPU or a programming terminal to access:

• Input voltage and current readings

• Output voltage and current for each output

• Temperature and status information

• Fault history and diagnostics

This feature enables remote monitoring of power supply health in critical applications.
