More Information

Overview Manuals Input Wiring Signal Filtering Module Status Installation

Features:

  • Accepts thirty-two discrete 24 VDC field inputs through one RX3i rack position.
  • Supports positive- or negative-logic wiring for compatible sensing devices.
  • Organizes the inputs into four groups of eight with separate group commons.
IC694MDL660 gives an RX3i controller a dense connection point for switches, sensors, and dry-contact interfaces.

Selectable input filtering lets IC694MDL660 reject bounce or electrical noise without forcing every installation to use the same response time.

When IC694MDL660 is replaced, the existing group commons, polarity, terminal assignments, and filter settings should remain aligned with the controller configuration.

The General Electric IC694MDL660 PACSystems RX3i 32-Point 24 VDC Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Field Signal Arrangement

  • Group Commons: Four eight-point groups let field returns be organized separately across the module.
  • Logic Polarity: Positive- or negative-logic devices require the matching common and signal direction.
  • Voltage Window: Field inputs operate from 0 to 30 VDC around a nominal 24 VDC system.
  • Terminal Transfer: Record each point and common before moving the removable wiring assembly to a replacement.

Response Tuning

  • Filter Choices: Configurable intervals range from 0.5 ms to 100 ms for the thirty-two input points.
  • Contact Bounce: A longer interval can prevent a mechanical contact from appearing as several rapid transitions.
  • Noise Rejection: Filtering can suppress short disturbances that do not represent a valid field-state change.
  • Timing Check: The chosen interval must still allow the controller to recognize events within the required machine response.

Input and Hardware Feedback

  • Point Indication: Front LEDs provide a direct view of the commanded state received at each input.
  • Controller Data: The RX3i reads the thirty-two point states through the module backplane interface.
  • Terminal Check: Module status information can identify whether the removable terminal assembly is present.
  • Revision Meaning: Status-bit interpretation differs between revision A and later IC694MDL660 hardware.

Rack and Replacement Planning

  • Rack Position: The module installs in a compatible PACSystems RX3i universal backplane slot.
  • Field Isolation: Keep each group common associated with its original eight input circuits.
  • Configuration Match: Logic polarity and filter values in the controller project must agree with the connected devices.
  • Revision Review: Confirm the complete catalog suffix and terminal-block compatibility before exchanging hardware.
Description
General Electric IC694MDL660 is a PACSystems RX3i discrete input module that brings thirty-two 24 VDC field signals into one universal backplane slot. Four groups of eight points organize the input bank around separate commons.

Positive- or negative-logic devices can connect to IC694MDL660 when signal polarity and the group common follow the selected wiring arrangement. Each active input draws approximately 7 mA at the nominal 24 VDC level.

Selectable filtering in IC694MDL660 offers intervals from 0.5 ms to 100 ms, allowing the controller to reject contact bounce or short electrical disturbances while preserving the response required by the machine sequence.

Front indicators on IC694MDL660 show active input points, and the removable terminal assembly keeps the four field groups organized. The module draws 300 mA from the 5 VDC backplane supply.

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.
How are the IC694MDL660 input points arranged for field wiring?
General Electric IC694MDL660 divides its 32 inputs into four groups of eight, so each group common and field polarity must be preserved during wiring.
Can IC694MDL660 receive both sourcing and sinking field signals?
IC694MDL660 supports positive- and negative-logic arrangements when the connected device polarity and group common are wired consistently.
Which IC694MDL660 setting helps stabilize a noisy input?
Selectable IC694MDL660 input filters from 0.5 ms through 100 ms can suppress bounce or noise; choose the interval that still meets the required response time.
What should be recorded before replacing IC694MDL660?
Save the IC694MDL660 rack slot, terminal assignment, group commons, polarity, filter settings, and hardware revision before disconnecting field wiring.
Why can an IC694MDL660 point remain off when 24 VDC is present?
For IC694MDL660, check the correct group common, device polarity, terminal contact, field return, filter setting, and controller configuration before replacing the module.
How should an IC694MDL660 replacement be matched?
Match the complete IC694MDL660 catalog number, revision, terminal block, RX3i rack compatibility, and the existing four-group wiring plan.
