Product Details:

The Emerson 1C31113G02 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 mv card is designed for ±50mV low-level signal collection from field thermocouples, capturing tiny voltage signals that reflect furnace and steam pipe temperature variations. It converts weak thermocouple analog signals into precise digital values and transmits measurement data to the Ovation controller for closed-loop calculation and real-time condition monitor of boiler and turbine thermal states. It adopts 13-bit measurement resolution to retain subtle temperature changes, supporting stable thermal monitoring for high-temperature industrial equipment. It continuously diagnoses channel working status, detecting broken sensor wires, 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 power transients transmitted from field cables, preventing measurement drift caused by industrial power noise. 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 1C31113G02 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 measurement, turbine hot section monitoring, chemical plant reactor thermal tracking and oil & gas pipeline automation, delivering reliable thermocouple signal acquisition and minimizing unexpected downtime of process production equipment.
