GE IC694MDL645 Series 90-40 Digital Output Module
Product Overview
The GE IC694MDL645 is a 16-channel digital output module designed for GE’s Series 90-40 PLC system. It serves as a critical interface between the PLC’s CPU and external industrial devices. The module converts digital control signals from the CPU into electrical outputs. These outputs activate devices such as relays, solenoid valves, contactors, and small motors. This functionality makes it essential for executing control logic in automation systems.
The GE IC694MDL645 supports 24V DC outputs. Each channel can deliver up to 0.5A of current. This allows it to control a wide range of low to medium-power devices. It is engineered with 250V AC isolation between the field devices and the PLC backplane. This isolation protects the PLC system from electrical noise and ground loops. Such protection is vital in industrial environments with heavy machinery.
As part of the Series 90-40 ecosystem, the GE IC694MDL645 integrates seamlessly with components like the IC694CPU325 (CPU module), IC694CHS392 (10-slot rack), and IC694PWR331A (power supply). It operates in temperatures from -10°C to 55°C. It resists dust, vibrations, and humidity. This ensures reliable performance in factories, automotive plants, and water treatment facilities.
The module features a compact design. It fits easily into standard Series 90-40 racks. LED indicators on the front panel show the output status of each channel (on/off). This simplifies troubleshooting. Whether used in small production lines or large industrial complexes, the GE IC694MDL645 ensures precise and timely control of external devices, enhancing overall system efficiency.

Main features and advantages
16-channel capacity: The IC694MDL645 offers 16 channels in a compact design, allowing control of multiple devices—such as solenoid valves on a packaging line or relays for lighting systems—in a single module. This reduces the number of modules needed in the rack, saving space in control cabinets.
reliable output performance: Each channel delivers up to 0.5A, with a 4A limit per bank of 8 channels. This makes the IC694MDL645 suitable for low to medium-power devices, from small motors to pneumatic actuators, without requiring external amplifiers.
industrial-grade isolation: 250V AC isolation between field devices and the backplane protects the PLC system from electrical noise and voltage spikes. This is critical in environments with heavy machinery, such as automotive factories, where electrical interference could cause erratic output behavior.
durability in harsh conditions: The IC694MDL645 operates in temperatures from -10°C to 55°C and resists dust, vibrations, and humidity. It performs reliably in challenging settings, from cold storage facilities to humid water treatment plants, reducing unplanned downtime.
easy integration: The module fits directly into Series 90-40 racks like the IC694CHS392, with a simple plug-in design that requires no special tools. It connects to the backplane for power and signals, minimizing wiring work during installation.
clear status monitoring: LED indicators on the front panel show the activation status of each channel (on/off). This allows technicians to quickly identify issues—such as a failed solenoid valve—without opening the control cabinet, speeding up troubleshooting.

Installation and maintenance
Pre-installation preparations: Power off the Series 90-40 rack (e.g., IC694CHS392) before installing the IC694MDL645. Check that the rack has an open slot and that the power supply (e.g., IC694PWR331A) provides 24V DC within the 18–30V range. Inspect the module for physical damage, ensuring connectors are clean and intact. Align the module with the slot and secure it using the locking clip to prevent loose connections.
Maintenance suggestions: Inspect the IC694MDL645 monthly. Check for loose wiring to connected devices and wipe dust from the module’s surface with a dry cloth. Monitor LED indicators to ensure channels activate as expected—consistently “off” when a signal is sent may indicate a wiring fault or a failed device. If a channel malfunctions, test the connected device first; if the issue persists, replace the IC694MDL645 following proper shutdown procedures to avoid damaging other components in the rack.
Application fields
The GE IC694MDL645 is widely used in industries requiring discrete output control:
In automotive manufacturing, it controls devices on assembly lines. For example, it activates robotic grippers (via relays) when a part is in position, as detected by input sensors connected to the IC694MDL240. The IC694MDL645 ensures precise timing, preventing misalignment and reducing production errors.
In food processing facilities, the IC694MDL645 operates conveyor belt motors and door interlocks. It activates the conveyor when a product is detected and closes interlocks to prevent access to hazardous areas during operation, enhancing worker safety and process efficiency.
In water treatment plants, it controls solenoid valves and pump contactors. When water levels reach a threshold (detected by float switches), the CPU sends a signal to the IC694MDL645, which opens or closes valves to regulate flow, preventing overflows and ensuring consistent treatment processes.
In packaging facilities, it triggers labeling machines and sealing devices. Signals from the CPU instruct the IC694MDL645 to activate these devices when a product reaches the packaging station, ensuring each item is labeled and sealed correctly, reducing waste.
