GE IC670MDL740K Genius Field Control Digital Input Module
Product Overview
The GE IC670MDL740K is a high-performance 16-channel digital input module designed for GE’s Genius Field Control and PACSystems RX3i automation platforms, serving as a critical interface for monitoring low-voltage discrete signals in industrial environments. Engineered to convert 24V DC signals from sensors, limit switches, and proximity detectors into digital data, the IC670MDL740K enables real-time monitoring of equipment status in manufacturing, energy, and water treatment sectors.
As part of the IC670 series, the GE IC670MDL740K integrates seamlessly with GE’s Genius Bus architecture, communicating via modules like IC670GBI002 (Bus Interface Unit) to share data with controllers such as IC697CPU780. Its 16 isolated channels (grouped into 4 groups of 4) provide 1500V AC isolation between field inputs and logic circuits, protecting against electrical noise and surges common in factory settings. With a 2-millisecond response time, the module ensures rapid detection of signal changes—critical for time-sensitive applications like emergency stop systems or conveyor jam detection.
The IC670MDL740K operates on 18–30V DC power from the Bus Interface Unit and accepts 24V DC inputs (10–30V DC on-state, 0–5V DC off-state), making it compatible with standard industrial sensors. Its IP65-rated housing resists dust, water splashes, and oil, while a -20°C to 70°C operating range suits harsh environments from cold storage to high-heat production lines. Compliance with UL 508 and IEC 61131-2 underscores its reliability in regulated industries, where precise input monitoring is key to process safety.

Main Features and Advantages
High-Density, Low-Voltage Compatibility
The IC670MDL740K’s 16 channels (in a compact 127mm × 89mm form factor) maximize I/O density in control cabinets, reducing space requirements in crowded industrial setups. Its 24V DC input range aligns with standard industrial sensors, eliminating the need for voltage converters and simplifying integration with legacy equipment—ideal for automotive plants using proximity detectors or food processing facilities with washdown-rated sensors.
Rapid Signal Processing
With a 2-ms response time, the module detects signal changes almost instantaneously, ensuring timely alerts for critical events like conveyor jams or emergency stops. This speed is vital in high-throughput environments such as packaging lines, where delays could lead to product damage or downtime.
Robust Isolation and Noise Resistance
1500V AC isolation between channels and logic circuits protects against ground loops and electrical noise from motors or welders, ensuring signal integrity in noisy environments like steel mills. This isolation extends the lifespan of connected components by preventing voltage spikes from reaching sensitive electronics.
Rugged Industrial Design
The IP65-rated front panel resists dust, water splashes, and oil, making the IC670MDL740K suitable for harsh settings—from humid water treatment plants to dusty cement factories. Its -20°C to 70°C operating range ensures reliability in extreme temperatures, eliminating the need for climate-controlled enclosures.
Seamless Integration and Hot-Swap Capability
The module connects directly to the Genius Bus via IC670GBI002, enabling plug-and-play integration with controllers like IC697CPU780. Its hot-swap functionality allows replacement without shutting down the system, minimizing downtime during maintenance—critical for 24/7 operations like power generation facilities.
Application Fields
The GE IC670MDL740K excels in industries requiring reliable low-voltage digital input monitoring:
- Automotive Manufacturing: Tracks robotic arm home positions, part presence sensors, and safety interlocks in assembly lines. Its fast response time ensures rapid shutdowns during collisions, protecting equipment and workers.
- Water Treatment: Monitors valve positions, pump run status, and level switches in filtration systems. The IP65 ratingwithstands humid, chemical-exposed environments, ensuring consistent performance.
- Packaging Automation: Detects bottle presence on conveyors and lid closure sensors in beverage plants. Its high channel density reduces the number of modules needed, lowering cabinet costs.
- Pharmaceutical Production: Monitors cleanroom door interlocks and equipment run signals, where low-voltage compatibility and noise resistance prevent false triggers that could disrupt sterile processes.
