GE IC693MDL231 Digital Input Module
Product Overview
The GE IC693MDL231 is a high-performance Digital Input Module designed for industrial automation systems, serving as a critical component of GE’s 90-30 Series Programmable Logic Controller (PLC) platform. Engineered to convert discrete input signals from field devices—such as switches, sensors, and relays—into digital data for processing by the PLC, this module ensures reliable and accurate signal acquisition in harsh industrial environments. As part of the IC693 Series, the IC693MDL231 offers seamless integration with other 90-30 Series components, including CPU modules and output modules, enabling scalable control solutions for manufacturing, power generation, and process industries.
Featuring a rugged industrial design, the GE IC693MDL231 supports 16 isolated digital input channels, each capable of handling 24 V DC signals with noise immunity and surge protection. Its sinking input configuration (NPN) ensures compatibility with a wide range of field devices, while built-in opto-isolation (250 V RMS) safeguards the PLC from electrical transients, extending module lifespan. The module’s LED indicators provide real-time status feedback for each channel, simplifying troubleshooting and maintenance. With an operating temperature range of -40°C to +70°C and compliance with industry standards like IEC 61131-2, the IC693MDL231 is ideal for applications requiring continuous operation in challenging environments, such as automotive plants, refineries, and material handling systems.
In automation ecosystems, the IC693MDL231 acts as the interface between field sensors and the PLC, translating physical states (e.g., switch positions, sensor activations) into digital commands for process control. Its hot-swappable design allows for module replacement without powering down the system, minimizing downtime during maintenance. By combining high-density input channels with advanced diagnostic capabilities, this module enhances system efficiency and reduces overall cost of ownership, making it a cornerstone of reliable industrial control strategies.

Key Features and Advantages
High-Density Input Channels: The IC693MDL231 accommodates 16 digital input channels in a compact form factor, maximizing space efficiency in control panels. This density is ideal for applications requiring extensive sensor monitoring, such as conveyor systems or automated assembly lines.
Robust Electrical Isolation: Each channel features 250 V RMS opto-isolation, protecting the PLC from voltage spikes and ground loops. This isolation ensures signal integrity in high-noise environments, such as those with electromagnetic interference from motors or power equipment.
Real-Time Diagnostics: LED indicators for each channel provide instant visual feedback on input status (on/off), while the module’s internal diagnostics monitor for open circuits and signal anomalies. This proactive monitoring reduces troubleshooting time and enables predictive maintenance, enhancing system availability.
Hot-Swap Capability: The module can be replaced while the PLC is operational, allowing maintenance without interrupting production. This feature is critical for 24/7 industrial processes where downtime equates to lost productivity.
Wide Environmental Tolerance: Designed to withstand extreme temperatures, vibration, and humidity, the IC693MDL231 ensures reliable performance in harsh settings. Its rugged enclosure and conformal-coated circuitry protect against dust, moisture, and corrosive elements, making it suitable for both indoor and outdoor installations.
Seamless System Integration: Compatible with GE’s 90-30 Series PLCs and programming software (e.g., VersaPro), the module simplifies system configuration. It supports daisy-chaining with other IC693 modules, enabling scalable solutions for small to medium-sized control systems without complex rewiring.
