GE IC694MDL632 Digital Input Module
Product Overview
The GE IC694MDL632 is a 16-channel digital input module designed for GE’s RX3i PACSystems, a versatile platform in industrial automation. This module serves as a critical link between field devices—such as limit switches, photoelectric sensors, and push buttons—and the PLC, converting their on/off signals into digital data that the PLC can process. It plays a key role in monitoring the status of equipment in automated systems, ensuring that processes run smoothly and safely.
As part of the IC694 Series, the GE IC694MDL632 integrates seamlessly with RX3i backplanes like the IC694CHS790 and works alongside 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 IC694MDL632 accepts 24 V DC input signals, with each channel capable of detecting dry contact closures or voltage signals from sensors. This makes it compatible with a wide range of industrial sensors commonly used in factories and processing plants.
Built to withstand harsh industrial environments, the GE IC694MDL632 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 noisy settings with large motors or high-voltage equipment. Though it is a legacy model, the GE IC694MDL632 remains essential for maintaining older RX3i systems, allowing businesses to extend the life of their automation infrastructure without full upgrades.

Main features and advantages
16-channel capacity: The IC694MDL632 offers 16 input channels, allowing it to monitor multiple sensors or switches 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 monitor 16 limit switches on a conveyor system, tracking the position of products at different stages.
24 V DC compatibility: The module accepts 24 V DC signals, the standard voltage for most industrial sensors. This compatibility means it can connect directly to photoelectric sensors, proximity switches, and push buttons without additional signal converters, reducing hardware costs.
Reliable isolation: Channel-to-backplane isolation (250 V AC) protects the module from electrical noise and ground loops. This is critical in environments with large motors or welding equipment, where voltage spikes can interfere with signal detection. The isolation ensures that false signals do not trigger incorrect PLC responses.
Tough industrial design: The IC694MDL632 operates in a wide temperature range and resists humidity and dust. This durability makes it suitable for use in food processing plants, automotive factories, and outdoor installations, where environmental conditions can be harsh.
Easy integration: The module fits into any I/O slot of RX3i backplanes, requiring no special tools for installation. It connects to sensors via simple 24 V DC wiring, with each channel clearly labeled on the terminal block for easy troubleshooting. This simplifies setup and reduces installation time.
Legacy system support: The IC694MDL632 is fully compatible with older RX3i systems, allowing businesses to keep using their existing hardware. This avoids the need to replace entire systems, saving money and minimizing downtime during upgrades.

Installation and maintenance
Pre-installation preparations: Verify that the IC694MDL632 is compatible with your RX3i backplane (such as the IC694CHS790) and CPU (such as the IC694CPU331). Ensure there is an empty I/O slot in the rack. 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 each sensor to the module’s terminal block, ensuring correct polarity (positive to signal, negative to common).
Maintenance suggestions: Inspect the IC694MDL632 quarterly for loose connections or dust buildup. Tighten any loose terminal screws to ensure good contact. Wipe dust from the module’s surface with a dry cloth to prevent overheating. Check the status LEDs—each channel has an LED that lights when a signal is detected. If a channel fails to detect a signal, check the sensor wiring and the sensor itself before replacing the module. Store a spare IC694MDL632 in a dry, cool area (10–30°C) to replace quickly if needed, minimizing downtime.
Application fields
The GE IC694MDL632 is widely used in industries that rely on RX3i PACSystems for automation:
- Automotive manufacturing: In car assembly plants, the module monitors proximity sensors on robotic arms, detecting when a part is in position for welding or fastening. Its 16 channels can track multiple sensors on a single robotic cell, providing real-time data to the PLC to coordinate movements.
- Food processing: In packaging lines, the IC694MDL632 connects to photoelectric sensors that detect the presence of bottles or packages. It sends signals to the PLC, which triggers filling or sealing machines to operate only when a product is present, reducing waste.
- Material handling: In warehouses, the module monitors limit switches on conveyor belts, signaling when a product reaches a transfer point. This allows the PLC to adjust conveyor speeds or redirect products, ensuring efficient movement through the facility.
- Water treatment: The IC694MDL632 tracks float switches in water tanks, detecting high or low levels. This data tells the PLC when to start or stop pumps, maintaining proper water levels in treatment processes.
In all these applications, the module’s reliability and compatibility make it a key component in maintaining consistent, efficient operations.
