Product Details:

The Emerson 1C31116G03 is an 8-channel rack-mounted analog input module built for Emerson Ovation distributed control systems, widely deployed in thermal power plants and heavy industrial process automation. This local powered card receives 0-20mA current signals from field pressure, flow and level transmitters. Unlike loop-powered modules, it supplies excitation power to the field transmitters from the DCS rack side, supporting current input measurement without relying on power from the field loop. It converts continuous analog current signals into 13-bit high-resolution digital data and transmits measurement values to the Ovation controller for closed-loop PID regulation and real-time process monitor of critical plant operating parameters. It continuously monitors channel health status, detecting wiring open-circuit, short-circuit and transmitter power failure 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 measurement deviation in electrically noisy industrial environments. 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 1C31116G03 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 flow and pressure parameter acquisition, turbine auxiliary instrument monitoring, chemical plant process variable tracking and oil & gas pipeline automation, delivering reliable local-powered current signal acquisition and minimizing unexpected downtime of process production equipment.
