GE IC693MDL634 Digital Input Module
Product Overview
The GE IC693MDL634 is a 16-channel digital input module designed for GE’s Series 90-30 PLC systems, a key platform in industrial automation. This module connects to sensors, switches, and other field devices, turning their physical states (like “on” or “off”) into digital signals that the PLC can process. It acts as a bridge between the physical world of machines and the digital world of the control system.
As part of the IC693 Series, the GE IC693MDL634 supports 24 V DC input signals, which is standard for most industrial sensors—such as limit switches, proximity sensors, and pushbuttons. Each of its 16 channels works independently, so a problem with one sensor won’t affect the others. The module fits into Series 90-30 backplane racks, like the IC693CHS393, and works with CPUs such as the IC693CPU364 to feed real-time data into the PLC.
Built to handle tough industrial conditions, the GE IC693MDL634 operates in temperatures from 0°C to 60°C and humidity up to 95% (non-condensing). This makes it reliable in factories, water treatment plants, and other harsh environments. Even though GE no longer produces it, the GE IC693MDL634 remains important for keeping older Series 90-30 systems running, helping businesses avoid the cost of full upgrades while maintaining smooth operations.

Main features and advantages
16 independent channels: The IC693MDL634 has 16 separate channels, so it can connect to 16 different sensors at once. This is useful in setups with many sensors—like a production line with multiple limit switches checking part positions. Each channel works on its own, so if one sensor fails, the others keep sending data.
Reliable signal handling: It uses 24 V DC input, which is common in industrial settings. This means it can connect to most standard sensors without needing extra adapters. The module also has 1500 V AC isolation between channels and the backplane, which blocks electrical noise from motors or other machines. This keeps sensor signals clear and accurate.
Tough for industrial use: The IC693MDL634 works in hot, cold, or damp places. It handles temperatures from 0°C to 60°C and high humidity, making it good for factories, outdoor pump stations, or dirty environments like foundries. Its solid build reduces the chance of breakdowns.
Easy to integrate: It fits right into Series 90-30 backplane racks. You slide it into an empty slot, and it connects automatically to the rack’s power and data lines. No special tools are needed, so installation is quick. It also works with all Series 90-30 CPUs, so it’s easy to add to existing systems.
Low power use: Each channel uses only 7 mA of current. This means the IC693MDL634 doesn’t strain the power supply, even when all 16 channels are in use. This is helpful in systems with many modules sharing one power source.
Installation and maintenance
Pre-installation preparations: Check that the IC693MDL634 is compatible with your Series 90-30 backplane rack (like the IC693CHS393) and CPU (like the IC693CPU364). Make sure there’s an empty slot in the rack. Turn off the PLC system before installing. Slide the module into the slot until it clicks into place. Connect sensors to the module’s terminals using 14–22 AWG wires, making sure positive and negative wires are hooked up correctly. Turn the system back on and check that the module’s status light is green, showing it’s working.
Maintenance suggestions: Check the IC693MDL634 regularly for dust or loose wires. Wipe dust off with a dry cloth to keep it from overheating. Tighten any loose terminal screws—loose connections can make sensor signals drop out. If a channel stops working, check the sensor first, then make sure the wire is tight in the module. Store a spare IC693MDL634 in a dry, cool area (10–30°C) so you can replace it fast if needed, keeping your system running with little downtime.

Application fields
The GE IC693MDL634 is used in many industries where sensors need to send data to a PLC:
- Manufacturing: In car factories, it connects to proximity sensors that check if parts are in the right position on the assembly line. The module sends this data to the PLC, which then tells robots when to start welding or fitting parts. Its 16 channels let it handle multiple sensors on one machine.
- Water treatment: It links to float switches in water tanks, telling the PLC when the tank is full or empty. This helps the PLC turn pumps on or off to keep water levels steady. The module’s ability to handle damp conditions keeps it working in wet treatment plants.
- Food processing: It connects to door switches on ovens or freezers, letting the PLC know if a door is open. If a door stays open too long, the PLC can sound an alarm to prevent energy waste or food spoilage. Its rugged design stands up to washdowns with cleaning chemicals.
- Material handling: In warehouses, it works with photoelectric sensors that detect if boxes are on a conveyor belt. The module sends this info to the PLC, which adjusts the conveyor speed to avoid jams. Its isolation feature blocks noise from conveyor motors, keeping signals reliable.
