FAQs

  • What is GE IC670MDL644?+
    The GE Fanuc IC670MDL644 is a 16-point, 24VDC positive/negative logic fast input module used within the GE Field Control distributed I/O system.
  • How do I wire the IC670MDL644?+
    The module supports both positive (source) and negative (sink) input logic. This means it can accept inputs where the sensor connects the input to common (0V) or to the +24V supply. The 16 points share a common terminal
  • What are the main functions of the IC670MDL644?+
    It receives 24VDC discrete signals from field devices (such as pushbuttons or limit switches) and converts them into logic level data for the Bus Interface Unit (BIU).
  • What is the response time?+
    It is a "fast" input module with a typical ON response of 25µs and a typical OFF response of 100µs.
  • What power IC670MDL644 required?+
    While it draws logic power (approx. 80mA) from the BIU, an external 24VDC supply is mandatory to power the field input devices.

Features:

  • 24 VDC Positive/Negative Fast Input Module
  • 16 discrete inputs
  • 250 VAC continuous, 1500 VAC for 1 minute
  • No isolation between individual points in a group
The 24 VDC Positive/Negative Fast Input Module (IC670MDL644) provides a single group of16 discrete inputs, which may be driven by positive or negative logic.

The IC670MDL644 24 Volts DC Positive/Negative Input Module is a Field Control Logic Fast Input Module made by GE Fanuc. It offers a single group of discrete inputs that can be driven by both positive and negative logic. The IC670MDL644 24 Volts DC Positive/Negative Input Module comes with 16 inputs, individual LEDs for the logic side inputs, and a "PWR" indicator LED to monitor the status of the power supply. The bus interface unit provides the power needed to drive the 5 Volts logic, and an external 24 Volts DC power supply is required to power up the input devices. It also provides isolation ratings such as 250 Volts AC of continuous user input to logic isolation and 1500 Volts AC of user input to frame ground isolation for 1 minute.

The IC670MDL644 GE Positive/Negative Fast Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

A network of resistors and capacitors establishes input thresholds and provides input filtering.Optoisolators provide isolation between the field inputs and the module’s logic components.Data from all 16 inputs is placed into a data buffer. The module’s circuit LEDs show thecurrent states of the 16 inputs in this data buffer.Parallel–to–seri al converters change input data from the data buffer into the serial formatneeded by the Bus Interface Unit.
  • Automobile Manufacturing:Powers assembly stations & QC checkpoints
  • Oil, Gas & Petrochemical:DCS: monitors valve positions & field status
  • Food and Beverage:Fast inputs for high-volume production throughput
  • Water Treatment & Utilities:Monitors pump stations & environmental equipment

Positioning: Tilt the I/O Terminal Block and hook the rear tabs over the top of the DIN rail.
Securing: Pivot the block downward until the spring-loaded latches click into place.
Clamping: Tighten the DIN rail clamp screw to a torque of 4 to 6 in/lbs (or up to 10 in/lbs depending on the specific block model) to prevent movement.
