GE IC694MDL741 Series 90-40 16-Channel Digital Input Module
Product Overview
The GE IC694MDL741 is a 16-channel digital input module designed for GE’s Series 90-40 PLC system. It acts as a key interface between industrial sensors, switches, and the PLC’s central processing unit. The module converts physical on/off signals from devices like proximity sensors, limit switches, and photoelectric detectors into digital data. This data is then sent to the CPU for processing, making it essential for monitoring equipment status in automation systems.
The GE IC694MDL741 operates with 24V DC input signals, a standard in industrial settings. It can handle input voltages ranging from 15V DC to 30V DC, allowing compatibility with most low-voltage sensors. Each channel is isolated from the PLC backplane with 250V AC protection. This isolation blocks electrical noise and ground loops, which are common in factories with heavy machinery. It ensures accurate signal detection even in noisy environments.
As part of the Series 90-40 ecosystem, the GE IC694MDL741 works seamlessly with components like the IC694CPU325 (CPU module), IC694CHS392 (10-slot rack), and IC694PWR331A (power supply). It functions in temperatures from -10°C to 55°C. It resists dust, vibrations, and humidity. This makes it reliable in industries such as automotive manufacturing, food processing, and water treatment.
The module has a compact design that fits easily into standard Series 90-40 racks. LED indicators on the front panel show the input status of each channel (on/off). This makes it easy to troubleshoot issues like broken wires or faulty sensors. Whether used in small production lines or large industrial plants, the GE IC694MDL741 ensures timely and accurate data collection, forming the basis of responsive automation control.

Main features and advantages
16-channel design: The IC694MDL741 has 16 channels in a small size. This lets it monitor 16 different sensors at once, such as 16 limit switches on a conveyor line. It reduces the number of modules needed in the rack, saving space in control cabinets.
Wide voltage range: The module works with 15V DC to 30V DC inputs, matching most industrial sensors that use 24V DC. This compatibility means it can replace older modules without changing existing sensors or wiring.
Electrical isolation: 250V AC isolation between field devices and the PLC backplane keeps electrical noise from affecting signal accuracy. This is important in factories with large motors or welders, where noise could cause false signals.
Tough for industrial use: The IC694MDL741 works in temperatures from -10°C to 55°C. It resists dust, vibrations, and moisture. It can handle harsh conditions like cold storage rooms or humid water treatment plants without failing.
Easy to install: The module fits into Series 90-40 racks like the IC694CHS392 with a simple plug-in design. No special tools are needed. It connects to the backplane for power and signals, cutting down on setup time.
Clear status lights: Each channel has an LED that lights up when a signal is detected. This makes it easy to see if a sensor is working. Technicians can spot issues like a loose wire or broken sensor without opening the cabinet, saving time on fixes.

Installation and maintenance
Pre-installation preparations: Turn off power to the Series 90-40 rack (e.g., IC694CHS392) before installing the IC694MDL741. Check that the rack has an open slot and that the power supply (e.g., IC694PWR331A) provides 24V DC. Look over the module for damage, and make sure connectors are clean. Slide the module into the slot and lock it in place. Connect sensors to the input terminals.
Maintenance suggestions: Check the IC694MDL741 once a month. Tighten any loose wires and wipe dust off the front with a dry cloth. Watch the LED indicators to make sure they light up when sensors are active. If a light stays off when it should be on, check the sensor and wiring. If the problem stays, replace the IC694MDL741 after turning off the rack power to avoid damaging other parts.
Application fields
The GE IC694MDL741 is used in many industries where monitoring on/off states is key:
In automotive plants, it tracks sensors on assembly lines. For example, proximity sensors detect when a car part is in place. The IC694MDL741 sends this signal to the IC694CPU325, which then tells a robot to pick up the part. This ensures parts are assembled in the right order.
In food processing, the IC694MDL741 monitors door interlocks on ovens and mixers. If a door is open, the sensor sends a signal to the module. The CPU uses this to stop the machine, preventing accidents and keeping workers safe.
In water treatment facilities, it watches float switches in storage tanks. When a tank is full, the switch triggers a signal to the IC694MDL741. The CPU then shuts off the inlet pump, stopping overflows and keeping water treatment on track.
In packaging plants, it checks photoelectric sensors that detect product presence. The IC694MDL741 sends signals to the CPU when a package moves past a point. This tells the CPU to activate a sealer or labeler, ensuring each package is processed correctly.
