Product Overview

The GE Fanuc IC693MDL740 is a 12/24 Volt DC Positive Logic (Sourcing) Discrete Output Module designed for the versatile Series 90-30 Programmable Logic Controller system. Featuring 16 high-speed output points arranged in two isolated groups of 8, this module supplies positive power directly from an external supply to connected load devices such as solenoids, indicators, relays, and motor starters. Weighing 0.35 kg (0.77 lbs), the IC693MDL740 offers an efficient single-slot form factor with built-in optocoupler isolation to protect backplane logic from field-side voltage transients.

Core Technical Advantages

  • High-Speed Sourcing Outputs: Delivers up to 0.5 Amps per channel across 16 output points with a swift 2 ms maximum ON/OFF response time, ideal for real-time process control.
  • High Inrush Handling: Built to withstand inductive load surges, supporting up to 4.78 Amperes of peak inrush current per group for 10 milliseconds.
  • Low Backplane Power Draw: Consumes a maximum of 110 mA from the internal 5V DC bus, preserving backplane power for adjacent I/O modules and processors.
  • Clear Field Diagnostics: Features 16 green LED status indicators on the front panel, providing immediate visual verification of channel logic states for easy troubleshooting.

Installation & Wiring Guidelines

  • Baseplate Slot Insertion: Align the 0.35 kg module with the card guides in any standard I/O slot of a Series 90-30 baseplate. Press firmly until the module is fully seated into the backplane, and swing the top/bottom retaining tabs into place.
  • Field Supply Connections: Connect the external +12/24V DC user power supply to the designated common terminals on the front terminal block. Verify correct polarity—positive logic requires the module to source positive voltage to the loads.
  • Inductive Load Suppression: When switching inductive loads like DC solenoids or relays, place a flyback diode directly across the load terminals to prevent back-EMF voltage spikes from damaging the output transistors.

Technical FAQs

Q1: What is the difference between positive logic (sourcing) and negative logic (sinking) on the IC693MDL740?
A1: The IC693MDL740 is a positive logic (sourcing) module, meaning its internal transistors switch positive voltage from the user power supply directly to the field load. Sinking (negative logic) modules, by contrast, switch the ground/negative side of the load.

Q2: Can I run 12V DC loads on one group and 24V DC loads on the other group?
A2: Yes. The 16 output points are divided into two separate, isolated groups of 8 points, each with its own common connection. This allows you to wire different external supply voltages to each group independently.

Q3: Does the IC693MDL740 require external user power to operate the output points?
A3: Yes. While the module's internal logic is powered by 110 mA from the PLC's 5V DC backplane, the actual field output currents (up to 0.5A per point) must be supplied by an external 12/24V DC field power supply.
