GE IC697MDL740

Product Overview

The GE Fanuc IC697MDL740 is a 24/48 VDC discrete output module for the Series 90-70 PLC platform. It provides 16 DC output points arranged in four isolated groups of four. The module is designed to interface the PLC with external loads such as contactors, relays, indicators, and other industrial devices.

Its sourcing output design and high inrush capability make it suitable for demanding industrial switching applications. The module also includes status indication and fuse monitoring to simplify troubleshooting.

Key Features

• 16 discrete DC output points.
• Four isolated groups provide flexible field wiring.
• Supports 24 or 48 VDC rated operation.
• Up to 2 A output current per point.
• High inrush capacity supports inductive loads.
• LED indicators show individual output status.
• A dedicated fuse indicator assists maintenance.
• Mechanical keying helps prevent incorrect module replacement.

Hardware Design

The module uses four groups of four outputs. Each group has individual fuse protection, while the front panel provides visual indicators for output and fuse conditions.

The high-current switching capability allows the module to control a broad range of field devices. Its electrical isolation also helps separate the output circuits from the PLC backplane and between output groups.

Typical Applications

This output module can be used in industrial PLC installations where DC switching is required. Common loads include:

• Motor starters
• Solenoids
• Interposing relays
• Indicator lamps
• Industrial actuators
• General machine-control devices

Its high inrush capability is particularly useful when connected loads require a temporary current surge during energization.

Installation and Maintenance

Before replacing the module, disconnect power according to the equipment's safety procedures. Confirm the wiring arrangement and field voltage before commissioning.

During maintenance, inspect the front-panel indicators and fuse status first. Check terminal connections for looseness, overheating, or corrosion. Keep the module clean and dry, and use suitable ESD precautions when handling it.

Configuration is performed through the PLC programming environment rather than through physical DIP switches or jumpers on the module.

Replacement Value

For facilities maintaining established Series 90-70 control systems, this module can serve as a practical replacement or spare. Keeping a compatible output module in inventory can help reduce downtime when an existing I/O channel develops a fault.
