Product Details:

The Emerson 1C31164G01 is a rack-mounted thermocouple input module built for Emerson Ovation distributed control systems, widely deployed in thermal power plants and heavy industrial process automation. This tc card receives millivolt signals from field thermocouple sensors, performing high-precision millivolt input measurement and converting weak voltage signals into accurate temperature readings for the Ovation controller. It supports multiple thermocouple types such as K, S, T and E type, and provides built-in cold junction compensation to eliminate measurement errors caused by terminal block temperature variation, ensuring reliable temp detect for boiler furnace temperature, turbine exhaust temperature and high-temperature reactor monitoring. Each channel can be independently configured for thermocouple type and fault alarm thresholds, offering flexible setup for multi-point high-temperature measurement in industrial plants. It continuously monitors channel health status, detecting open sensor, short-circuit and wiring break faults, and sends diagnostic alerts to the Ovation operator workstation for maintenance scheduling. Built-in galvanic isolation and noise suppression circuits filter electromagnetic interference and transient voltage noise from long field sensor cables, preventing signal distortion and protecting internal precision measurement circuits. Industrial-grade high-precision millivolt acquisition components and rugged reinforced PCB layout are adopted, featuring strong anti-vibration performance and stable long-term operation under environments with dust, humidity and temperature fluctuation. It uses standard rack slot plug-in structure for simple installation and fast replacement during on-site maintenance, effectively cutting down equipment maintenance downtime. The Emerson 1C31164G01 cooperates with Ovation termination bases, CPU modules and rack power supplies to build complete Ovation DCS process control solutions. It is widely used in boiler furnace temperature monitoring, turbine exhaust thermal measurement, chemical plant high-temperature reactor tracking and oil & gas pipeline automation, delivering dependable thermocouple temperature acquisition and minimizing unexpected downtime of process production equipment.
