GE IC694MDL754-CD

Product Overview

GE IC694MDL754-CD is a PACSystems RX3i 32-point discrete output module designed for industrial automation systems. It provides positive-logic, sourcing outputs for 12/24 VDC loads and includes electronic short-circuit protection (ESCP). The -CD revision uses firmware version 1.20 and is backward compatible with earlier versions.

This module is designed for high-density digital output applications where multiple field devices need reliable DC switching from a PLC control system.

Technical Parameters

The published technical documentation specifies optical field-to-backplane isolation and group-to-group isolation of 250 VAC continuous, with 1500 VAC isolation for one minute.

Main Features

• 32 discrete DC output channels
• 12/24 VDC nominal operation
• 0.75 A output capability per point
• Positive-logic sourcing design
• Electronic short-circuit protection
• Automatic recovery after certain fault conditions
• Two electrically isolated output groups
• Individual point-level diagnostic capabilities
• Compatible with RX3i control architecture

Internal Design

The module combines 32 solid-state output channels with protection and diagnostic circuitry. The outputs are arranged in isolated groups, allowing different field-side power arrangements to be used where the application requires them.

Each output incorporates electronic protection against excessive current and short circuits. The module also monitors field-side conditions and communicates diagnostic information back to the controller.

Application Areas

Typical applications include:

• Factory automation
• Machine control
• Motor and actuator switching
• Solenoid control
• Industrial production lines
• Material handling systems
• Process automation

Its high channel density can help reduce the number of individual output modules required in a control cabinet.

Installation & Maintenance

The module requires a compatible high-density terminal block, such as the IC694TBB032 or IC694TBS032. It can be installed in an RX3i I/O slot and requires an RX3i CPU with the appropriate firmware support.

Before replacement, verify the CPU firmware, terminal block, field voltage, wiring, and output-load requirements. Always follow appropriate electrical safety and ESD procedures when installing or servicing the module.
