GE IC670MDL740 Digital Input Module
Product Overview
The GE IC670MDL740 is a high-performance Digital Input Module designed for GE’s 90-70 Series PLC platform, catering to industrial automation systems that require reliable and precise signal acquisition. 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 accurate and noise-free operation in harsh industrial environments. As part of the IC670 Series, the IC670MDL740 offers seamless integration with other 90-70 components, including CPU modules and output modules, enabling robust control solutions for manufacturing, power generation, and process industries.
Featuring a rugged industrial design, the GE IC670MDL740 supports 16 isolated digital input channels, each capable of handling 24 V DC signals with built-in surge protection to withstand transient voltage spikes. Its sinking input configuration (NPN) ensures compatibility with a wide range of field devices, while optical isolation (2500 V RMS) between channels and ground 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 an operating temperature range of -40°C to +70°C and compliance with industry standards like IEC 61131-2, the IC670MDL740 is ideal for applications requiring continuous operation in challenging environments, such as offshore platforms, refineries, and heavy machinery setups.
In automation ecosystems, the IC670MDL740 serves as the interface between field devices and the PLC, translating physical switch states or sensor signals 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 Signal Acquisition: The IC670MDL740 supports 16 input channels in a compact form factor, maximizing space efficiency in control panels. This density is ideal for applications requiring multiple signal inputs, such as conveyor systems, packaging machinery, or robotic cells.
Robust Electrical Isolation: Each channel features 2500 V RMS optical isolation, protecting the PLC from voltage surges and ground loops. This ensures reliable operation in high-noise environments, such as those with large motors or power equipment.
Real-Time Diagnostics: LED indicators for each channel provide instant visual feedback on input status (on/off), while built-in diagnostic circuitry monitors for signal loss, overvoltage, and channel failures. 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 IC670MDL740 ensures reliable performance in harsh conditions. Its rugged enclosure and conformal-coated circuitry protect against dust, moisture, and corrosive elements.
Seamless System Integration: Compatible with GE’s 90-70 Series PLCs and programming software (e.g., Cimplicity Machine Edition), the module simplifies system configuration and integration. It supports daisy-chaining with other IC670 modules, enabling scalable solutions for small to large control systems.
