GE IC694MDL660-BC Series 90-40 32-Channel Digital Output Module
Product Overview
The GE IC694MDL660-BC is a high-density 32-channel digital output module designed for GE’s Series 90-40 PLC system, serving as a critical interface to convert digital control signals from the PLC’s CPU into electrical outputs that activate industrial devices. It is engineered to control a wide range of low to medium-power equipment, such as relays, solenoid valves, contactors, and small motors, making it essential for executing automation logic in complex industrial setups.
The GE IC694MDL660-BC operates with 24V DC outputs, delivering up to 0.5A per channel with a maximum of 4A per group of 8 channels. This capacity allows it to handle multiple devices simultaneously, reducing the number of modules needed in control racks. It features 250V AC isolation between field devices and the PLC backplane, protecting against electrical noise and ground loops common in factories with heavy machinery—ensuring reliable signal transmission even in noisy environments.
As part of the Series 90-40 ecosystem, the GE IC694MDL660-BC integrates seamlessly with core components like the IC694CPU325 (CPU module), IC694CHS392 (10-slot rack), and IC694PWR331A (power supply). It operates in temperatures from -10°C to 55°C, resists dust, vibrations, and humidity, and fits compactly into standard Series 90-40 racks. LED indicators on the front panel show the output status of each channel (on/off), simplifying troubleshooting. Whether used in large manufacturing lines or automated warehouses, the GE IC694MDL660-BC ensures precise and efficient control of industrial devices.

Main features and advantages
high channel density: The IC694MDL660-BC offers 32 channels in a compact form, allowing control of twice as many devices as 16-channel modules. This reduces the number of modules needed in the rack, saving space in crowded control cabinets—ideal for large-scale systems like automotive assembly lines with dozens of actuators.
reliable output capacity: Each channel delivers up to 0.5A, with 4A per 8-channel group, making the IC694MDL660-BC suitable for low to medium-power devices. It can control solenoid valves, small motors, and relays without external amplifiers, simplifying system design.
industrial-grade isolation: 250V AC isolation between field devices and the backplane shields the PLC from electrical noise and voltage spikes. This is critical in environments with welders, motors, or other noisy equipment, ensuring the IC694MDL660-BC does not misfire due to interference.
durability in harsh conditions: The IC694MDL660-BC 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 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 valve or loose wire—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 IC694MDL660-BC. 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 IC694MDL660-BC monthly. Check for loose wiring to connected devices and wipe dust from the 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 IC694MDL660-BC following proper shutdown procedures to avoid damaging other components in the rack.
Application fields
The GE IC694MDL660-BC is widely used in industries requiring high-density digital control:
In automotive manufacturing, it controls devices on large assembly lines. The IC694MDL660-BC activates robotic grippers, conveyor motors, and door interlocks based on signals from input modules. Its 32 channels allow control of multiple stations from one module, simplifying rack layout.
In food processing facilities, the IC694MDL660-BC operates packaging machines, filling valves, and conveyor systems. It activates filling valves when sensors detect an empty container, then triggers sealing devices—ensuring precise, synchronized packaging and reducing waste.
In water treatment plants, it controls solenoid valves, pump contactors, and alarm systems. When water levels or chemical concentrations reach thresholds, the CPU sends signals to the IC694MDL660-BC to adjust valves or activate alarms, maintaining compliance with safety standards.
In logistics and warehousing, the IC694MDL660-BC controls conveyor diverters, sorters, and door locks in automated warehouses. Its 32 channels manage multiple devices, ensuring packages are routed correctly and storage areas are secure.
