GE IC694MDL240 Series 90-40 Digital Input Module
Product Overview
The GE IC694MDL240 is a 16-channel digital input module designed for GE’s Series 90-40 PLC system, serving as a critical interface for receiving digital signals from industrial sensors and switches. It converts these physical signals (such as “on/off” states from proximity sensors or limit switches) into digital data that the PLC’s CPU can process, enabling real-time monitoring and control of machinery in automation systems.
As a key component in the Series 90-40 ecosystem, the GE IC694MDL240 integrates seamlessly with core components like the IC694CPU325 (CPU module), IC694CHS392 (10-slot rack), and IC694PWR331A (power supply). It supports 24V DC inputs, a standard in industrial settings, and features 250V AC isolation between field devices and the PLC backplane, protecting against electrical noise and ground loops common in factories.
The GE IC694MDL240 is built to withstand harsh industrial conditions. It operates in temperatures from -10°C to 55°C, resists dust and vibrations, and functions reliably in environments with frequent electrical fluctuations—making it ideal for automotive plants, food processing facilities, and water treatment centers. Its compact design (110mm × 64mm × 30mm) fits easily into standard Series 90-40 racks, while LED indicators for each channel provide instant status updates (signal detected or fault), simplifying troubleshooting.
Whether used to monitor conveyor belt positions, detect part presence, or track valve states, the GE IC694MDL240 ensures accurate and timely data collection, forming the foundation of responsive and efficient automation systems.

Main features and advantages
16-channel capacity: The IC694MDL240 offers 16 channels in a compact form, allowing monitoring of multiple sensors—such as proximity switches on an assembly line or limit switches on a conveyor—in a single module. This reduces the number of modules needed in the rack, saving space in control cabinets.
24V DC compatibility: Designed for 24V DC inputs (with a 15–30V range), the IC694MDL240 works with the most common industrial sensors and switches, eliminating the need for signal converters. This simplifies wiring and reduces system complexity.
Electrical isolation: Features 250V AC isolation between field devices and the backplane, protecting against electrical noise from motors, welders, or other heavy machinery. This ensures accurate signal detection even in noisy environments like automotive factories.
Durable industrial design: Operates reliably in temperatures from -10°C to 55°C and resists dust, vibrations, and humidity. It performs consistently in harsh settings—from cold storage facilities to hot manufacturing floors—without needing special enclosures.
Clear status monitoring: LED indicators on the front panel show the input state of each channel (on/off), making it easy to identify issues like a failed sensor or loose wire. Technicians can troubleshoot without opening the control cabinet, saving time.
Easy integration: Fits directly into Series 90-40 racks (e.g., IC694CHS392) with a simple plug-in design, requiring no special tools for installation. It connects to the rack’s backplane for power and data, reducing wiring work during setup.
Installation and maintenance
Pre-installation preparations: Power off the Series 90-40 rack (e.g., IC694CHS392) before installing the IC694MDL240. Check that the rack has an open slot and that the power supply (e.g., IC694PWR331A) provides 24V DC within the 15–30V range. Inspect the module for physical damage, ensuring connectors are clean and intact. Use a screwdriver to secure the module in the rack, aligning it with the backplane pins.
Maintenance suggestions: Inspect the IC694MDL240 monthly. Check for loose wiring connections and wipe dust from the front panel with a dry cloth to keep LED indicators visible. Monitor the LEDs to ensure channels show correct states—consistently “off” for an active sensor may indicate a wiring fault or failed sensor. If a channel malfunctions, test the sensor with a multimeter first; if the issue persists, replace the IC694MDL240 following proper shutdown procedures to avoid damaging other components.
Application fields
The GE IC694MDL240 is widely used in industries requiring discrete signal monitoring:
In automotive manufacturing, it monitors sensors on assembly lines. For example, it detects when a car part is in position (via a proximity sensor) and sends this signal to the IC694CPU325. The CPU then triggers the next step in assembly, such as activating a robotic gripper—ensuring smooth, synchronized production.
In food processing facilities, the IC694MDL240 tracks the state of conveyor belt gates and door interlocks. It detects if a gate is open (via a limit switch) and sends a signal to the CPU, which pauses the conveyor to prevent contamination or worker injury.
In water treatment plants, it monitors float switches in storage tanks. When a tank reaches maximum level, the switch triggers a “on” signal to the IC694MDL240, which the CPU uses to shut off inlet pumps—preventing overflows and ensuring compliance with safety standards.
In packaging facilities, it monitors photoelectric sensors that detect product presence on a line. Signals from the IC694MDL240 tell the CPU when to activate labeling machines or sealers, ensuring each package is processed correctly.
