The General Electric IC670MDL644 is a high-performance 16-point discrete input module designed for the GE Field Control I/O system. Engineered for rapid signal processing, this module supports both positive and negative logic configurations, providing flexibility for various industrial control applications. It features integrated LED status indicators for each input channel and a dedicated power status LED for the field supply.

Features

• 16 discrete input channels in a single group.
• Supports both positive and negative logic (source/sink).
• Fast response time: 25µs typical ON response.
• Integrated optoisolation between field inputs and internal logic.
• Status LEDs provide visual confirmation of input states and power health.
• Requires external 24VDC power for field devices.

Applications

• Automotive assembly line monitoring and quality control checkpoints.
• Oil, gas, and petrochemical facility valve position monitoring.
• High-speed manufacturing and packaging lines requiring fast signal throughput.
• Water treatment and utility infrastructure for remote pump and sensor monitoring.

Technical Specifications

Installation Guidelines

• Ensure all power is disconnected from the Bus Interface Unit and field supply before installing or removing the module.
• To mount, tilt the I/O terminal block and hook the rear tabs securely over the top of the DIN rail.
• Pivot the assembly downward until the spring-loaded latches engage with an audible click.
• Tighten the DIN rail clamp screw to ensure the module is firmly seated and prevented from lateral movement.
• Maintain proper cable routing to separate signal wires from high-voltage or high-EMI sources to ensure signal integrity.

FAQ

What is the primary function of the IC670MDL644?

The IC670MDL644 acts as a bridge between field devices, such as limit switches or proximity sensors, and the GE Field Control Bus Interface Unit, converting 24VDC signals into digital data.

Does this module require external power?

Yes, while the module draws logic power from the internal bus, an external 24VDC power supply is required to energize the field-side input devices.

Can this module be used with different logic types?

Yes, the module is designed to support both positive (source) and negative (sink) logic, allowing for versatile integration into existing control architectures.
