IC693MDL752 GE Fanuc Series 90-30 5/12-24V DC Output Module

Product Overview

The GE Fanuc IC693MDL752 is a high-density, 32-point discrete output module engineered for the Series 90-30 PLC system. Operating as a positive logic (sourcing) module, it provides fast switching control for user loads across four isolated output groups (8 points per group). Designed for maximum versatility in automated assembly lines and control networks, the IC693MDL752 supports dual operational modes: 5 VDC TTL logic or standard 12–24 VDC output loads. Weighing approximately 0.30 kg (0.66 lbs), this compact single-slot module interfaces via two 24-pin high-density connectors on the front panel.

Technical Specifications

Key Design & Hardware Features

• Dual Mode Support (TTL & DC): Easily configurable to drive 5V TTL integrated circuits or standard 12–24V industrial relays, solenoids, and indicators.
• High-Speed Switching Response: Extremely fast 0.5 ms transition times ensure millisecond-accurate timing control for high-speed machine operations.
• Status LED Array: Equipped with dual-color or multi-point LED status indicators for real-time channel diagnostics and rapid field troubleshooting.
• Compact High-Density Footprint: Provides 32 points in a single Series 90-30 rack slot, conserving backplane space and reducing overall cabinet footprint.

Installation Guidelines

1. Connector Layout: Point connections are split between two 24-pin front connectors (Connector A for Group 1/2 and Connector B for Group 3/4). Ensure pre-wired cable assemblies are securely locked to prevent intermittent connection loss.

2. Power Supply Selection: An external user-supplied power supply is required to energize field loads in DC mode. Wire external power independently to each isolated group common.

3. Noise Protection: Inductive field loads (e.g., solenoids, contactors) should be equipped with external flyback diodes across the load terminals to suppress voltage transients.

Frequently Asked Questions (FAQs)

Q1: What is the main difference between TTL Mode and DC Mode on the IC693MDL752?
A1: TTL Mode regulates output signals to 5 VDC logic level (25 mA max), ideal for semiconductor circuits, whereas DC Mode supports standard 12–24 VDC field devices up to 0.5 A per channel.

Q2: Can I mix TTL and DC loads on different groups within the same module?
A2: Yes. The 32 output points are divided into four isolated 8-channel groups, allowing independent power supply connections for each group based on field requirements.

Q3: Does the IC693MDL752 feature built-in short circuit protection?
A3: The IC693MDL752 includes basic thermal and current protection, but standard external fast-acting fuses are recommended on field supply lines to protect output transistors from prolonged overload conditions.
