The General Electric IC670MDL740 is a 16-point discrete output module, engineered as part of the Field Control I/O series. This module provides 16 positive logic (sourcing) output channels, designed to interface with 24VDC control systems. It is optimized for distributed I/O applications, offering a compact footprint and reliable switching for industrial automation tasks.

Features

• 16-point positive logic output configuration.
• Operating voltage range: 10-30 VDC (24 VDC nominal).
• Maximum load current capacity of 0.5 Amps per point.
• Integrated status LED indicators for individual output channel monitoring.
• Bus Interface Unit (BIU) compatible for modular expansion.
• DIN-rail mountable design for efficient cabinet space utilization.
• Integrated 25-terminal block supporting AWG #14 to #22 wire gauges.

Applications

• Actuator and solenoid valve control in fluid or pneumatic systems.
• Driving interposing relay coils for high-power load switching.
• Powering pilot lamps and visual status indicators on control panels.
• Integration into distributed I/O architectures for machine and process automation.

Technical Specifications

Installation Guidelines

• Ensure the system power is disconnected before installing or removing the module from the DIN-rail.
• Verify that the BIU power supply matches the 111 mA current draw requirement.
• Use appropriate wire gauges (AWG #14-22); ensure terminal screws are tightened to secure connections.
• Maintain proper clearance for ventilation to prevent overheating in dense rack configurations.
• Follow standard ESD (Electrostatic Discharge) mitigation practices when handling the module circuitry.
• Confirm the positive logic configuration matches your field device requirements before energizing.

FAQ

Is the IC670MDL740 still supported?

While this unit may be designated as End-of-Life (EOL) by the manufacturer, it remains a functional component in many legacy GE Field Control systems. We continue to provide access to these modules for maintenance and system support.

Can I use this module for AC loads?

No, the IC670MDL740 is specifically a DC output module (10-30 VDC). For applications requiring AC load switching, consider the IC670MDL930 relay module.

What should I do if my load exceeds 0.5A?

If your specific application requires higher current, please refer to the IC670MDL742 (1.0A per point) or the IC670MDL730 (2.0A per point) modules for compatibility.
