Product Introduction & Supply Chain Strategy
The GE Fanuc / Emerson IC693MDL655 is a high-density, 32-point 24 VDC discrete input card for the Series 90-30 controller family. Designed for high-speed automated processes, it features a fast 1 ms response time and accepts both positive (sinking) and negative (sourcing) field logic configurations. Unlike standard 16-point input modules that use screw terminals, the IC693MDL655 uses dual high-density 24-pin front connectors to maximize I/O density per rack slot.
Because the entire Series 90-30 hardware line has been fully discontinued by the OEM, maintaining an IC693MDL655 as New Surplus is an essential risk-mitigation strategy. Refurbished I/O cards frequently suffer from degraded optocoupler chips, cracked connector pins, or damaged internal resistor networks caused by past overvoltage events. Sourcing factory-fresh New Surplus stock ensures intact optical isolation and reliable high-speed signal processing, keeping your legacy control system running smoothly without costly re-engineering.
Installation & Configuration Guide
1.Pre-Installation (Prep & Safety):Safety measures and wiring pinout prep.
Isolate all 24 VDC field power and rack power using standard LOTO procedures. Put on a grounded ESD wrist strap before unboxing the IC693MDL655 module. Review the 24-pin cable pinout diagram (Connectors A and B) and confirm whether your field sensors require positive (sink) or negative (source) common wiring.
2.Removal:Safe extraction techniques for high-density I/O modules.
Unscrew and unlatch the dual 24-pin ribbon/wiring connectors from the front panel of the existing module. Press the top module release tab on the Series 90-30 baseplate slot, pivot the top of the card forward away from the backplane, and lift the bottom hook out of the rack rail.
3.Installation (Clone & Seat):Hardware mounting and cable connection.
Hook the bottom lip of the new IC693MDL655 onto the lower slot rail of the Series 90-30 baseplate. Pivot the card upward and press firmly until the top retaining latch clicks securely into the rack slot. Re-attach the dual 24-pin cables to ports A and B, ensuring side locking clips engage tightly.
4.Power-On & Testing:Power-up and LED signal validation.
Re-energize the PLC rack and 24 VDC field power supplies. Verify the Module Status indicator on the CPU. Actuate connected field devices (limit switches, sensors) and check the front-panel LEDs (A1–A16, B1–B16) to ensure rapid, accurate state transitions in logic.

Firmware/Software Versions & Upgrade Notes
- Software Support: Configured via Logicmaster 90-30, VersaPro, or Proficy Machine Edition (PME).
- Configuration Requirement: In hardware configuration (HW Config), select the
IC693MDL655module catalog number under the designated baseplate slot to assign 32 consecutive discrete input bits (%I addresses). - Wiring Harness Note: Because this module uses dual 24-pin high-density connectors rather than a terminal block, use standard pre-wired cable harnesses (such as IC693CBL300 or field terminal blocks IC693ACC337) to simplify wiring and avoid pin crossover errors.
Frequently Asked Questions (FAQ)
Is the completely new and unused?
Yes. This product is a Brand New Surplus unit. It is not used, pulled, or refurbished. All units undergo thorough quality verification before delivery. Factory packaging is opened solely for visual inspection, pin check, and anti-counterfeit serial verification.
What is the advantage of a “Fast” input module like the over standard input modules?
Standard 24 VDC input modules usually have a hardware input filter time of 7 ms to 20 ms to filter out contact bounce. The features a 1 ms response time, making it ideal for high-speed applications such as pulse counting, fast-moving optical sensors, and rapid packaging machinery.
Can I mix positive and negative logic on the same module?
The contains 32 inputs divided into two isolated 16-point groups (Group A and Group B). While all 16 points within a single group must share the same wiring configuration (either all positive logic or all negative logic), Group A and Group B can be wired independently if needed.
What terminal connector does the use?
Instead of a removable terminal block, the module has two 24-pin male connectors on the front panel. It accepts standard pre-fabricated GE 24-pin connector cables or terminal block breakout kits.
How does stocking this module protect against unexpected downtime?
Since the Series 90-30 PLC platform is obsolete, finding immediate direct replacements during a failure can take days or weeks. Holding 1 or 2 units of the in your spare parts stock guarantees drop-in recovery, keeping your production line moving.
What warranty coverage is included with this module?
We support this fast input module with a full 1-year functional replacement warranty. If any channel failure, optocoupler defect, or logic fault occurs under standard operating conditions within 12 months, we will immediately supply a direct replacement unit from our stock.
