The General Electric IC670MDL740 is a 16-point discrete output module, engineered as part of the Field Control series. This module provides positive logic (sourcing) outputs, specifically designed for distributed I/O applications where reliable DC signal control is required for industrial automation tasks.
Features
- Sixteen (16) positive logic output channels.
- Operating voltage range of 10-30 VDC (24 VDC nominal).
- Maximum load current of 0.5 Amperes per channel, with a 4 Ampere total module capacity.
- Integrated status LED indicators for individual channel monitoring.
- Common fuse protection with a dedicated "fuse blown" diagnostic LED.
- Compact design suitable for DIN-rail mounting in distributed architectures.
Applications
- Direct control of DC solenoids and pneumatic valve manifolds.
- Interface for industrial pilot lamps, status indicators, and alarm beacons.
- Activation of interposing relay coils for higher power load switching.
- Distributed I/O integration for machine automation, such as packaging and conveyor systems.
- Remote signal distribution in water and wastewater infrastructure.

Installation Guidelines
- Ensure the system power is completely disconnected before installing or removing the module from the terminal base.
- The module mounts onto a standard DIN-rail; ensure it is securely seated to maintain proper electrical contact with the Bus Interface Unit (BIU).
- Use appropriate wire gauges (AWG 14-22) for terminal connections. If using external jumpers, restrict wire size to AWG 14-16.
- Maintain proper clearance for ventilation to prevent overheating during high-current operation.
- Handle with standard ESD precautions to prevent damage to internal circuitry.
FAQ
What is the primary function of the IC670MDL740?
This module provides 16 discrete sourcing outputs for the GE Field Control system, allowing a PLC or controller to drive DC-powered devices like solenoids, relays, and indicators.
Can this module handle AC loads?
No, the IC670MDL740 is designed exclusively for DC applications (10-30 VDC). For mixed AC/DC switching, consider the IC670MDL930 relay module.
What should I do if my load exceeds 0.5A per point?
For higher current requirements, consider cross-referencing to the IC670MDL742 (1.0A per point) or the IC670MDL730 (2.0A per point) depending on your specific load needs.
