Description
Product Introduction
The GE Fanuc IC693MDL732 is an 8-point 12/24 Volt DC Positive Logic (Sourcing) Discrete Output Module for GE Series 90-30 PLC systems. Occupying a single option slot on any CPU, expansion, or remote baseplate, it translates internal PLC logic states into solid-state DC switching outputs to control field loads like solenoids, indicator lights, motor starter coils, and small DC contactors.
Featuring electronically protected transistor outputs, the IC693MDL732 provides sourcing currents up to 0.5 Amps per point. The 8 output points share a single common power bus and ground return, backed by optical isolation between the field-side voltage and the internal PLC backplane. A hinged door on the front houses an 8-LED status bar for fast visual diagnostic monitoring during operation.

Application Scenarios & The “Trench” Experience
At 1:15 AM on a high-speed bottling line, a hydraulic diverter gate stopped firing, causing cases to pile up at the casing junction. The LED for point 3 on the installed output card was lit solid green, but measuring voltage at the terminal block showed 0 VDC—an unsuppressed inductive kickback from an aging solenoid coil had burned out the sourcing transistor channel on the output card. With the diverter stuck mid-position, the entire line sat locked out, accruing over $3,000 per hour in idle factory costs.
Application Scenarios
- Pneumatic & Hydraulic Solenoids: Controls 12/24VDC directional control valves, air cylinders, and fluid manifolds.
- Control Relay & Contactor Coils: Actuates intermediate pilot relays, motor contactors, and interlock coils.
- Annunciator & Status Lights: Drives stack lights, panel indicator LEDs, and local alarm horns.
- Discrete Speed Command Inputs: Provides solid-state run/stop and direction inputs to Variable Frequency Drives (VFDs) and servo drives.
Field Case Study
A packaging automation facility in Texas suffered a sudden station shutdown when a shorted coil on a labeling machine ruined output points on their legacy IC693MDL732 card. The line was completely halted, stalling downstream cartoning operations. We pulled a fully bench-tested, pre-cleared surplus IC693MDL732 module from inventory and dispatched it via hot-shot courier. The site technician powered down the rack, swung the wired 20-pin terminal block onto the replacement card, slotted it into option slot 3, and restored full production within 12 minutes of delivery.

Transparency SOP: Quality Assurance & Testing
We test every IC693MDL732 unit under live load on active GE test racks before it enters our ready-to-ship inventory.
- Inbound Visual Verification: Inspection for casing cracks, bent card-edge backplane pins, intact terminal block latches, and OEM tag authenticity.
- Backplane Power-On Check: Slotted into an active GE Series 90-30 rack (IC693CHS392 driven by an IC693PWR330 supply) to confirm power-up and backplane communication.
- 8-Point Full Load Switching Test: Applied a 24VDC field supply and connected a 0.5A inductive load across all 8 channels individually and simultaneously to confirm clean transistor switching, low ON-state voltage drop, and LED activation.
- Thermal Soak & Stress Test: Executed continuous high-frequency output cycling under full 2A total current load for 4 hours inside a thermal test chamber to ensure zero transistor thermal breakdown.
- ESD Sealing & Final QC: Cleaned, terminals verified, and sealed inside heavy-duty ESD shielding with custom impact-resistant protective foam packaging.
The Veteran’s Tech Trap Guide
- ⚠️ Utilize the Removable Terminal Block: You do not need to unscrew your field wires when swapping a failed ! The module features a 20-terminal removable connector block. Simply loosen the top/bottom retaining screws, pop off the wired terminal block, swap the module, and snap the block onto the replacement unit.
- ❗ Never Hot-Swap on the Baseplate: The GE Series 90-30 backplane is not hot-swappable! Inserting or pulling the while the rack power supply is energized can arc backplane pins, ruin internal backplane transceivers, or trigger an immediate CPU hardware fault. Always kill rack power first.
- ⚠️ Always Install Flyback Diodes on Inductive Loads: When driving inductive loads (solenoid coils, relay coils, magnetic brakes), always place a reverse-biased flyback diode (such as a 1N4004) directly across the coil terminals. Inductive back-EMF spikes can exceed transistor breakdown voltages and permanently ruin individual channels.
- ❗ Mind the 2.0A Total Module Limit: While each individual point can handle up to 0.5A, the total combined current for all 8 points simultaneously must not exceed 2.0 Amps at elevated temperatures. If your application requires high continuous current on all 8 points simultaneously, evaluate load distribution or external interposing relays.
Frequently Asked Questions (FAQ for Conversion)
Q: Is the GE Fanuc hot-swappable?
A: No. You must turn off main power to the Series 90-30 baseplate before removing or installing the module to prevent backplane or chip damage.
Q: Is the a sinking or sourcing output module?
A: The is a positive logic (sourcing) module. It switches the positive voltage (+12/24VDC) from the external power supply to the load terminal.
Q: Can I drive 120VAC loads directly with the ?
A: No. The is strictly rated for 12 to 30 VDC. To switch 120VAC loads, you must use a relay output card (like the IC693MDL940) or an AC output card (like the IC693MDL340).
Q: Do I need to re-program the PLC when replacing an ?
A: No. As long as the replacement unit matches the model number and is installed in the same option slot, no software reconfiguration or ladder logic editing is required.
Q: What warranty coverage comes with this surplus output card?
A: Every module comes backed by a full 12-month replacement warranty. All units are authentic GE Fanuc surplus equipment, thoroughly inspected, cleaned, and bench-tested under live 24VDC loads prior to shipping.
