GE IC670MDL330J

Product Overview

The GE Fanuc IC670MDL330J is a Field Control discrete output module designed for switching AC loads in industrial automation systems. It provides 16 grouped discrete outputs and supports a rated voltage range of 12 to 120 VAC. The Series J version is listed as a 120 VAC, 16-point Field Control output module.

The module receives its operating power from the Bus Interface Unit (BIU), while an external AC source supplies power to the connected field loads. This architecture allows the module to operate as part of a distributed I/O station.

Technical Specifications

The 1 A rating applies to each point, while the total module load is limited to 4 A with appropriate derating.

Key Features

• 16 discrete AC output points.
• 12–120 VAC rated operating range.
• Up to 1 A per output point.
• 4 A maximum total module load.
• Individual LEDs indicate output status.
• Built-in protection features support AC load switching.
• Designed for GE Fanuc Field Control distributed I/O systems.
• BIU-based system communication and power architecture.

Hardware Structure

The module contains the output switching circuitry, status indicators, protection components, and interface electronics required for connection to the Field Control system. Individual logic-side LEDs provide visual indication of the status of each output.

The module communicates through the Bus Interface Unit. The Field Control architecture transfers two bytes of discrete output data to represent the 16 output points.

Applications

The IC670MDL330J can be used in industrial automation systems where AC field devices need discrete ON/OFF control. Typical applications include:

• Factory automation
• Industrial machine control
• Motor and contactor control
• Indicator and lamp switching
• Distributed I/O stations
• Legacy GE Fanuc control systems

Its grouped output design makes it important to verify the field wiring and common-group configuration before replacement.

Installation and Maintenance

Disconnect field power before removing or inserting the module. The GE Field Control documentation specifically warns against removing or inserting external modules while power is applied.

During maintenance, verify the module number, Series J revision, terminal connections, field voltage, and connected load. ESD precautions should also be used when handling an uninstalled module.

For replacement projects, check the complete Field Control station configuration and BIU compatibility before commissioning the new module.
