GE IC694MDL916 Digital Input/Output Module
Product Overview
The GE IC694MDL916 is a combined digital input/output module designed for GE’s RX3i PACSystems, a versatile platform in industrial automation. This module serves as a critical interface between the PLC and field devices, integrating 8 digital inputs and 8 digital outputs in a single compact unit. It enables simultaneous monitoring of sensor signals (via inputs) and control of actuators (via outputs), making it ideal for applications requiring a balanced mix of input and output capabilities in a space-efficient design.
As part of the IC694 Series, the GE IC694MDL916 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 IC694MDL916 supports 24 V DC inputs and outputs, with each output channel capable of handling up to 2 A of current, making it suitable for driving a wide range of industrial devices, from small sensors to medium-sized actuators.
Built to withstand harsh industrial conditions, the GE IC694MDL916 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 IC694MDL916 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
Combined I/O design: The IC694MDL916 integrates 8 inputs and 8 outputs in a single module, reducing the number of modules needed in a system. This saves space in the backplane rack and simplifies wiring, making it ideal for applications with limited space or a balanced mix of sensors and actuators. For example, it can monitor 8 proximity sensors and control 8 solenoid valves in a small packaging machine.
24 V DC compatibility: The module supports 24 V DC inputs and outputs, the standard voltage for most industrial sensors and actuators. This means it can connect directly to devices like limit switches, photoelectric sensors, and small motors without additional power converters, reducing hardware costs and setup time.
High-current outputs: Each output channel handles up to 2 A, making the IC694MDL916 suitable for driving larger devices such as relays, contactors, and small motors. This versatility allows it to control a wide range of industrial equipment directly, without the need for additional amplifiers.
Channel isolation: The IC694MDL916 features channel-to-backplane isolation (250 V AC), protecting against electrical noise and ground loops. This ensures that a fault in one channel (e.g., a shorted sensor) does not affect others, maintaining system reliability in noisy industrial environments.
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, food processing plants, and outdoor installations. This durability ensures consistent performance in challenging conditions.
Easy integration: The IC694MDL916 fits into any I/O slot of RX3i backplanes, requiring no special tools for installation. Its terminal block is clearly labeled, simplifying wiring—each input and output 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 IC694MDL916 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 sensors to the input terminals and actuators to the output terminals, ensuring correct polarity (positive to signal terminal, negative to common terminal).
Maintenance suggestions: Inspect the IC694MDL916 monthly for loose wires or dust. Tighten terminal screws to ensure good contact—loose connections can cause inputs to malfunction or outputs to fail. Wipe dust from the module’s surface with a dry cloth to prevent overheating. Check channel LEDs: for inputs, a lit LED indicates a detected signal; for outputs, a lit LED indicates an active output. If a channel fails, test the connected device first; if the device works, replace the module. Store a spare IC694MDL916 in a dry, cool area (10–30°C) to replace quickly if needed, minimizing downtime.
