Product Brief:

1C31161G02 is Emerson Ovation high‑accuracy RTD electronics module G02 hardware revision for high‑precision thermal‑resistance temperature signal acquisition

It is plugged onto matched I/O base unit must work together with corresponding RTD personality module to complete sensor type and wiring‑mode hardware definition

This electronic module adopts 20‑bit high‑resolution ADC architecture converts field RTD resistance variation into stable digital temperature data for Ovation controller processing

High‑precision measuring performance satisfies strict thermal‑process boiler metal temperature turbine‑shaft temperature and high‑accuracy temperature monitoring requirements

Built‑in lead‑wire resistance compensation eliminates measuring error caused by long‑distance field cable resistance

Built‑in open‑circuit and short‑circuit detection monitors field channel faults for quick on‑site fault locating

On‑board LED indicators display power channel working and module fault status convenient for on‑site troubleshooting

The module supports hot‑swap operation can be replaced online without system shutdown for convenient site maintenance

This is EOL discontinued spare part widely used for maintenance and renovation of thermal power plant Ovation DCS system

Please confirm matched RTD personality module and I/O base unit before purchase

Strict ESD anti‑static protection shall be followed during installation and replacement
