GE Fanuc IC693MDL750 32-Point Negative Logic Output Module

Product Overview

The GE Fanuc IC693MDL750 is a high-density 32-point negative logic (sinking) discrete output module engineered for the Series 90-30 Programmable Logic Controller (PLC) system. Designed to drive solenoids, relays, indicators, and other DC field loads across a 12V to 24V DC voltage range, it switches the load return side directly to the negative DC bus. Weighing a lightweight 0.16 kg (approx. 0.35 lbs) with dimensions of 128 × 30 × 120 mm, this compact module offers high I/O packing density while drawing a minimal 21 mA current from the 5V DC backplane.

Key Advantages

• High-Density 32-Point Architecture: Maximizes control cabinet space by supporting 32 individual sinking output channels in a single Series 90-30 chassis slot.
• Lightweight & Compact Footprint: Weighing only 0.16 kg, the module simplifies slot installation without placing mechanical stress on the backplane baseplate.
• Rapid Response Switching: Delivers ultra-fast state execution with a maximum switching time of 2 ms, ideal for time-critical automation loops.
• Robust Signal Isolation: Features 1,000 VAC optical isolation between the field-side wiring and internal backplane logic to safeguard system electronics.
• Industrial Noise Immunity: Complies with EN 61000-6-2 standards to protect against electromagnetic interference in severe electrical environments.

Frequently Asked Questions

Q1: What does "Negative Logic" (Sinking) mean for field wiring?

A1: In a negative logic configuration, the output channel acts as a current sink. When an output point turns ON, it provides a path to the negative DC return (0V), pulling current through the connected field load from the positive power supply.

Q2: What type of wiring connector is required for this 32-point module?

A2: Due to its high pin density and lightweight 0.16 kg frame, the IC693MDL750 utilizes a multi-pin high-density ribbon or cable connector on the front panel rather than standard screw terminal blocks.

Q3: Is external power required to operate the output channels?

A3: Yes. While the internal logic is powered by drawing 21 mA from the 5V DC backplane, an external 12–24V DC user power supply must be connected to power the field-side output devices.
