Product Details:

The Emerson 1C31161G02 is a rack-mounted RTD input module built for Emerson Ovation distributed control systems, widely deployed in thermal power plants and heavy industrial process automation. This rtd card is optimized for 3-wire RTD sensor connections and receives resistance signals from PT100 and other resistance temperature detectors to complete high-precision temp measurement. It converts raw resistance values into accurate temperature readings and applies built-in linearization algorithms to compensate sensor characteristic curves, minimizing measurement error caused by cable resistance for boiler and turbine temperature monitoring. Each channel supports independent configuration for sensor type and alarm thresholds, giving engineers flexible setup for multi-point thermal monitoring in power and chemical facilities. 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 measurement drift and protecting internal precision measurement circuits. Industrial-grade high-precision resistance measurement 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 1C31161G02 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 tube temperature monitoring, turbine bearing temperature protection, chemical plant reactor thermal monitoring and oil & gas pipeline automation, delivering dependable 3-wire RTD temperature acquisition and minimizing unexpected downtime of process production equipment.
