GE IC694MDL753B Digital Output Module
Product Overview
The GE IC694MDL753B is a 32-channel digital output module designed for GE’s RX3i PACSystems, a robust platform in industrial automation. This module serves as a critical link between the PLC and field devices, converting digital signals from the PLC into electrical outputs to control equipment such as motors, valves, solenoids, and alarms. It enables precise, real-time control of multiple devices, making it essential for maintaining efficient and safe automated processes.
As part of the IC694 Series, the GE IC694MDL753B 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 IC694MDL753B provides 24 V DC sinking outputs, with each channel capable of handling up to 0.5 A of current (8 A total for the module), making it suitable for driving a wide range of small to medium-sized industrial actuators commonly used in factories and processing plants.
Built to withstand harsh industrial conditions, the GE IC694MDL753B operates in temperatures from 0°C to 60°C and humidity up to 95% (non-condensing). It features group isolation (250 V AC between channel groups and backplane) 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 IC694MDL753B 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
32-channel high density: The IC694MDL753B offers 32 output channels, allowing it to control twice as many devices as 16-channel modules while occupying a single slot in the backplane. This reduces the number of modules needed, saving space in control cabinets and simplifying wiring. For example, it can control 32 solenoid valves in a food processing line, each activating at specific stages of packaging.
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 an 8 A total limit for the module. This is sufficient to power devices like conveyor motors, hydraulic valves, and alarm buzzers, making the IC694MDL753B versatile for various industrial tasks.
Group isolation: The IC694MDL753B features 8-channel group isolation (250 V AC), protecting against electrical noise and ground loops. This ensures that a fault in one group of channels (e.g., from a shorted valve) does not affect others, maintaining system reliability in noisy environments with large machinery.
Tough industrial design: The module operates in a wide temperature range and resists humidity and dust, making it suitable for harsh settings like automotive factories (with oil and debris) or outdoor installations (exposed to weather). This durability ensures consistent performance in challenging conditions.
Easy integration: The IC694MDL753B fits into any I/O slot of RX3i backplanes, requiring no special tools for installation. Its terminal block is clearly labeled, simplifying wiring—each channel corresponds to a specific terminal, easing 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 IC694MDL753B 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 IC694MDL753B 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 IC694MDL753B in a dry, cool area (10–30°C) to replace quickly if needed, minimizing downtime.
Application fields
The GE IC694MDL753B is widely used in industries requiring control of multiple devices:
- Automotive manufacturing: In car assembly plants, the module controls 32 robotic grippers and welding clamps across an assembly line. It receives signals from the PLC to open/close grippers or activate clamps, ensuring parts are held securely during welding or fastening.
- Food and beverage processing: In bottling facilities, the IC694MDL753B operates 32 filling valves and conveyor motors. It triggers these devices based on input from sensors (connected to modules like the IC694MDL660), ensuring bottles are filled and moved efficiently without spillage.
- Water treatment: In wastewater plants, the module controls 32 pump motors and valve actuators. It adjusts pump speeds or valve positions based on water level data from analog sensors, regulating flow through filtration systems to maintain treatment efficiency.
- Material handling: In warehouses, the IC694MDL753B controls 32 conveyor belt motors and diverter valves. It adjusts motor speeds or redirects packages based on input from barcode scanners, ensuring goods are sorted and shipped correctly.
In all these applications, the module’s high channel count and reliability make it a key component in maintaining smooth, efficient operations.
