GE IC694MDL740A Digital Output Module
Product Overview
The GE IC694MDL740A is a 16-channel digital output module designed for GE’s RX3i PACSystems, a leading platform in industrial automation. This module converts digital signals from the PLC into electrical outputs to control external devices such as motors, valves, solenoids, and alarms, acting as a critical link between the PLC’s processing unit and field equipment.
As part of the IC694 Series, the GE IC694MDL740A integrates seamlessly with RX3i backplanes like the IC694CHS790 and works with CPUs such as the IC694CPU331. It fits into any I/O slot of the backplane, drawing power through the rack and communicating with the CPU via the backplane bus. The IC694MDL740A provides 24 V DC sinking outputs, with each channel capable of handling up to 0.5 A of current (4 A total for the module), making it suitable for driving small to medium-sized industrial actuators.
Built to withstand harsh industrial conditions, the GE IC694MDL740A operates in temperatures from 0°C to 60°C and humidity up to 95% (non-condensing). It features channel-to-backplane isolation (250 V AC) to protect against electrical noise and ground loops, ensuring reliable operation even in environments with large motors or high-voltage equipment. Though it is a legacy model, the GE IC694MDL740A remains vital for maintaining older RX3i systems, allowing businesses to extend the life of their automation infrastructure without costly full upgrades.

Main features and advantages
16-channel control: The IC694MDL740A offers 16 output channels, allowing it to control multiple devices—such as motors, valves, and alarms—with a single module. This reduces the number of modules needed in a system, saving space in the backplane rack and simplifying wiring. For example, it can control 16 solenoid valves in a packaging line, each activating at specific stages of the process.
24 V DC compatibility: The module provides 24 V DC outputs, the standard voltage for most industrial actuators. This means it can connect directly to small motors, relays, and indicator lights without additional power converters, reducing hardware costs and setup time.
Reliable current handling: Each channel handles up to 0.5 A, with a 4 A total limit per group. This is enough to power devices like conveyor motors or hydraulic valves, making the IC694MDL740A versatile for various industrial tasks.
Group isolation: The IC694MDL740A features 4-channel group isolation (250 V AC), protecting against electrical noise and ground loops. This is critical in environments with large machinery, where voltage spikes can disrupt signals. Isolation ensures that a fault in one group of channels does not affect others, maintaining system reliability.
Tough industrial design: The module operates in temperatures from 0°C to 60°C and resists humidity and dust. This durability makes it suitable for harsh settings like automotive factories (with oil and debris) or food processing plants (with washdowns), ensuring consistent performance in challenging conditions.
Easy integration: The IC694MDL740A fits into any I/O slot of RX3i backplanes, requiring no special tools for installation. Its terminal block is clearly labeled, making wiring straightforward—each channel corresponds to a specific terminal, simplifying troubleshooting. It communicates with the PLC via the backplane bus, so no extra programming is needed to recognize it.
Installation and maintenance
Pre-installation preparations: Verify that the IC694MDL740A is compatible with your RX3i backplane (e.g., IC694CHS790) and CPU (e.g., IC694CPU331). Ensure there is an empty I/O slot. Power off the system and disconnect all power sources. Align the module with the slot and push firmly until it clicks into place. Connect the 24 V DC power supply to the backplane’s terminal block. Wire devices to the module’s terminal block, matching each device to a channel (positive to signal terminal, negative to common terminal).
Maintenance suggestions: Inspect the IC694MDL740A monthly for loose wires or dust. Tighten terminal screws to ensure good contact—loose connections can cause devices to malfunction. Wipe dust from the module’s surface with a dry cloth to prevent overheating. Check channel LEDs: a lit LED indicates an active output, helping identify faulty wiring or devices. If a channel fails, test the connected device first; if the device works, replace the module. Store a spare IC694MDL740A in a dry, cool area (10–30°C) to replace quickly if needed, minimizing downtime.
Application fields
The GE IC694MDL740A is widely used in industries requiring precise control of electrical devices:
