GE IC697MDL750 90-70 Series Digital Input Module
Product Overview
The GE IC697MDL750 is a high-reliability Digital Input Module designed for industrial automation systems, serving as a key component of GE’s 90-70 Series PLC platform. Engineered to convert discrete input signals from field devices (e.g., switches, sensors, relays) into digital data for processing by the PLC, this module ensures precise and noise-free signal transmission in harsh industrial environments. As part of the IC697 Series, the IC697MDL750 integrates seamlessly with other 90-70 Series components, such as CPU modules and output modules, enabling scalable and robust control solutions for power generation, oil & gas, and manufacturing sectors.
Featuring a rugged industrial design, the GE IC697MDL750 supports 16 isolated digital input channels, each capable of handling 24 V DC signals with surge protection to withstand transient voltage spikes. Its sinking input configuration (NPN) ensures compatibility with a wide range of field devices, while built-in optical isolation (2500 V RMS) protects the PLC from electrical noise and ground loops. The module’s LED indicators provide real-time status feedback for each channel, simplifying troubleshooting and maintenance. With a wide operating temperature range (-40°C to +70°C) and compliance with industry standards like IEC 61131-2, the IC697MDL750 is ideal for applications requiring continuous operation in challenging environments, such as offshore platforms, refineries, and heavy manufacturing facilities.
In automation ecosystems, the IC697MDL750 acts as the interface between field devices and the PLC, translating physical switch states or sensor outputs into digital signals for control logic execution. 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 IC697MDL750 supports 16 digital input channels in a compact form factor, maximizing space efficiency in control panels. This density is ideal for applications requiring multiple sensor inputs, such as conveyor systems, robotic cells, or complex manufacturing lines.
Robust Electrical Isolation: Each input channel features 2500 V RMS galvanic isolation, protecting the PLC from voltage surges and ground loops. This ensures reliable operation in high-noise environments, such as those with heavy machinery or power-intensive equipment.
Surge Protection and Noise Immunity: Built-in surge protection diodes and filtering circuitry safeguard the module against transient voltage spikes, while anti-aliasing filters reduce false inputs from electrical noise. This reliability minimizes unplanned downtime and maintenance costs.
Real-Time Diagnostics: LED indicators for each channel provide instant visual feedback on input status (on/off), while the module’s diagnostic circuitry monitors for open circuits, short circuits, and signal anomalies. This proactive monitoring reduces troubleshooting time and enhances system availability.
Hot-Swap Capability: The module can be replaced while the PLC is running, allowing maintenance without interrupting operations. This feature is critical for 24/7 industrial processes where downtime translates to lost productivity.
Wide Environmental Tolerance: Designed to withstand extreme temperatures, vibration, and humidity, the IC697MDL750 meets rigorous industry standards (e.g., IEC 60068-2-6 for vibration resistance). Its rugged enclosure and conformal-coated circuitry protect against dust, moisture, and corrosive elements.
