GE Fanuc IC693MDL752 32-Point 5/12/24VDC Negative Logic (Sinking) Output Module

Module Overview

The IC693MDL752 is a high-density discrete output module designed for the GE Fanuc Series 90-30 PLC system. This component provides 32 sinking output points, specifically engineered to interface with low-power DC field devices or TTL-level logic circuits. Organized into four isolated groups of eight points each, the IC693MDL752 offers significant space savings in the PLC rack while maintaining electrical separation between different control circuits.

Detailed Technical Specifications

This module is versatile, supporting both standard 12/24VDC industrial voltages and 5VDC TTL applications. Note that current capacities vary significantly based on the operating mode selected.

Operational and Engineering Notes

When configuring the IC693MDL752, engineers must account for the high-density wiring required by 32 points. Unlike 8 or 16-point modules with screw terminals, this module typically utilizes high-density connectors. It is critical to ensure the external power supply matches the logic levels of the field equipment. Since this is a "Negative Logic" module, the PLC completes the circuit to the negative rail (Common), meaning the load must be pre-wired to the positive DC voltage source.

Typical Application Scenarios

• TTL Interfacing: Driving 5V semiconductor logic, microcontrollers, or high-speed electronic gates that require low-current switching.

• Control Room Panels: Managing large arrays of LED indicator lamps and small annunciators where rack space is limited.

• Legacy Upgrades: Replacing multiple low-density modules to free up slots in a Series 90-30 baseplate without changing the field logic.

Technical FAQ

Can I mix 5V and 24V signals on the same IC693MDL752 module?

Yes, provided the different voltages are isolated by group. Each of the four groups has its own common, allowing you to run TTL signals on one group and 24VDC on another, assuming proper wiring practices are followed.

Does this module require a specific fuse for protection?

The module is designed for low-current applications. While it has internal protection, it is best practice to use external fuses for each group common terminal, especially when operating in the 12/24VDC mode at 2.0A per group.
