Product Details:

The Emerson 1C31113G03 is an 8-channel rack-mounted low-level analog input module designed for Emerson Ovation distributed control systems, widely deployed in thermal power plants and heavy industrial process automation. This 100mv card collects weak low-level voltage signals up to 100mV from field thermocouples and temperature sensors, performing precise thermal sensing to capture subtle temperature variations in furnaces, steam pipelines and reactor equipment. It converts raw millivolt analog signals into 13-bit high-resolution digital data and transmits measurement values to the Ovation controller for closed-loop control and real-time temp measurement of critical plant assets. The module supports stable reading of low-amplitude sensor signals and minimizes measurement drift caused by ambient temperature fluctuation, ensuring reliable thermal data for boiler and turbine monitoring. It continuously runs channel diagnostic checks, detecting broken sensor wiring, open-circuit and short-circuit faults, and sends diagnostic alerts to the Ovation operator workstation for maintenance scheduling. Built-in galvanic isolation and noise filtering circuits block electromagnetic interference and voltage transients from field cables, preventing signal distortion and preserving accuracy for delicate low-level input. Industrial-grade precision analog 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 1C31113G03 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 acquisition, turbine hot component monitoring, chemical plant reactor thermal tracking and oil & gas pipeline automation, delivering dependable low-level signal acquisition and minimizing unexpected downtime of process production equipment.
