General Electric IC670MDL740 Field Control 16-Point Discrete Output Module

The General Electric IC670MDL740 is a 16-point discrete output module engineered for the Field Control distributed I/O system. This unit provides positive logic (sourcing) outputs, specifically designed to interface with 24VDC control devices such as pilot lamps, solenoid actuators, and relay coils. As a compact, DIN-rail mountable component, it is ideal for space-constrained industrial control cabinets requiring reliable, high-density I/O expansion.

Features

• 16-point positive logic discrete output architecture.
• Supports a wide operating voltage range of 10-30 VDC (24 VDC nominal).
• Maximum output current capacity of 0.5 Amps per channel, with a 4 Amp total module limit.
• Individual status LED indicators for each channel to facilitate rapid diagnostics.
• Integrated fuse protection with a dedicated blown-fuse status indicator.
• Compact, modular design compatible with standard Field Control terminal bases.

Applications

• Actuator & Valve Control: Efficiently drives DC solenoids and pneumatic manifold valves in fluid systems.
• Industrial Signaling: Powers pilot lamps, status indicators, and audible alarms on control panels.
• Relay Switching: Ideal for activating interposing relays to control higher-load external equipment.
• Machine Automation: Suitable for integration into conveyor sorting systems, packaging machinery, and textile equipment.

Technical Specifications

Installation Guidelines

• Ensure the Bus Interface Unit (BIU) is powered down before installing or removing the module from the terminal base.
• Mount the module onto a standard DIN-rail, ensuring secure seating to maintain electrical connectivity.
• Verify that the external fuse is properly rated (5 Amp, 250 V, 5x20mm) to protect against output shorts.
• Use appropriate wire gauges (AWG 14-22) and ensure terminals are tightened to prevent intermittent connections.
• Maintain proper spacing for ventilation to prevent thermal buildup within the enclosure.
• Route signal wiring away from high-EMI sources, such as VFDs or high-voltage power lines, to prevent signal noise.

FAQ

What is the primary function of the IC670MDL740?

It is a discrete output module that provides 16 channels of 24VDC sourcing output for controlling industrial devices like solenoids and relays within a GE Field Control system.

Can this module handle AC loads?

No, the IC670MDL740 is designed strictly for DC applications (10-30 VDC). For mixed-voltage requirements, consider a relay output module such as the IC670MDL930.

What should I do if my load exceeds 0.5A per channel?

If your application requires higher current, refer to the IC670MDL742 (1.0A per point) or the IC670MDL730 (2.0A per point) for higher capacity requirements.

How is the module protected against overcurrent?

The module includes an integrated 5 Amp, 250 V slow-acting fuse with a visual LED indicator to signal when the fuse has blown.
