More Information

Overview Manuals Wiring Indicators Installation Application
  • Sixteen 24 V DC inputs share one commoned field group
  • Positive-logic or negative-logic wiring can be selected for the field circuit
  • Seven-millisecond typical on and off response supports general discrete sensing

IC694MDL645 is a General Electric PACSystems RX3i digital input module designed for 24 V DC field-state acquisition.

The module maps current at any of its sixteen inputs to the controller input table and provides one green status indicator for each point.

Before installation or replacement, verify the commoned-group polarity, field-device voltage and current, terminal assignments, power source, isolation requirement, and saved RX3i configuration.

Availability, condition, price, and shipping time for IC694MDL645 are confirmed during quotation.

  • Terminals 2 through 17 connect input points 1 through 16
  • Terminal 1 is the documented common connection for the sixteen-point group
  • Terminals 18 and 19 provide the documented 24 V OUT and 0 V OUT connections
  • Sixteen green LEDs show the on or off state of input points 1 through 16
  • Current entering an input point produces a logic 1 in the controller input-status table
  • The blue label band identifies IC694MDL645 as a low-voltage module
  • IC694MDL645 can be installed in any I/O slot of a PACSystems RX3i system
  • Remove the field-side terminal block before hot extraction and reinstall it after insertion
  • Using 24 V OUT for field devices reduces the documented isolation rating to 50 V AC continuous and 500 V AC for 1 minute
  • Pushbutton status acquisition in PACSystems RX3i machine-control systems
  • Limit-switch position feedback for discrete automation sequences
  • Electronic proximity-switch monitoring with compatible 24 V DC field circuits
Description
IC694MDL645 is a General Electric PACSystems RX3i 24 V DC positive/negative-logic input module for rack-based control systems.

The unit provides sixteen inputs in one commoned group, 0 to +30 V DC input capability, and 7 ms typical on and off response.

Before installation or replacement, confirm the complete catalog number, field polarity, single-common wiring, input-device characteristics, terminal block, power source, isolation, and saved configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can General Electric IC694MDL645 be wired for either positive or negative logic?
Yes. The official manual documents positive- or negative-logic wiring. Preserve the single common group and follow the applicable manufacturer field-wiring diagram.
Which field devices are documented for General Electric IC694MDL645?
The manufacturer identifies pushbuttons, limit switches, and electronic proximity switches as compatible device examples when their voltage and current characteristics match the module.
What input levels does General Electric IC694MDL645 recognize?
The documented on-state range is 11.5 to 30 V DC with at least 3.2 mA; the off-state range is 0 to +5 V DC with no more than 1.1 mA.
What changes when General Electric IC694MDL645 powers field devices from 24 V OUT?
The field-to-backplane and frame-ground isolation rating changes to 50 V AC continuous and 500 V AC for 1 minute, so the wiring and safety review must account for that reduction.
Can General Electric IC694MDL645 be removed while the RX3i backplane is energized?
Hot insertion and removal are documented only with the field-side terminal block removed before extraction and reinstalled after the module is seated.
What should be checked if one General Electric IC694MDL645 point remains off?
Compare the point LED and input table, then check the terminal assignment, common, field polarity, device output, voltage, current, and wiring continuity.
What information should accompany an inquiry for General Electric IC694MDL645?
Provide the complete catalog number, required hardware revision if applicable, field logic, input-device type, terminal-block details, power source, quantity, and clear label photographs.
