Product Overview
The GE IC697VRD008 RTD/Strain Gauge Bridge Module is a high-precision Analog Input Module designed for the GE Fanuc Series 90-70 PLC platform. Engineered for industrial process measurement, the module acquires signals from Resistance Temperature Detectors (RTDs) and strain gauge bridge sensors, converting them into digital data that can be processed by the PLC for accurate monitoring, control, and automation.
Installed within a compatible Series 90-70 PLC rack, the IC697VRD008 communicates with the PLC CPU through the high-speed backplane while continuously sampling temperature and strain signals from connected field devices. The module performs signal conditioning, analog-to-digital conversion, filtering, and diagnostic monitoring, ensuring stable and accurate measurements even in electrically noisy industrial environments.
By supporting both RTD temperature sensors and strain gauge bridge transducers, the module enables a wide range of measurement applications, including temperature monitoring, weighing systems, load measurement, force monitoring, pressure measurement, tank weighing, structural monitoring, and industrial process control.
The rugged industrial design allows reliable operation under vibration, electrical interference, humidity, and continuous-duty production conditions. Typical applications include manufacturing automation, power generation, oil and gas, chemical processing, pharmaceutical production, food and beverage manufacturing, mining, water treatment, and material handling systems.
With dimensions of 200 × 40 × 150 mm and an approximate weight of 0.93 kg, the IC697VRD008 integrates seamlessly into existing Series 90-70 PLC systems while providing dependable long-term measurement performance.
