Product Brief:

1C31164G04 is Emerson Ovation RTD personality module G04 hardware revision works paired with 1C31161 series electronic modules

It is plugged onto I/O base together with host module defines 4‑channel hardware interface for 4‑wire Pt100 thermal‑resistance signal acquisition

This personality module adopts 4‑wire wiring scheme achieves full lead‑wire resistance compensation further eliminates measurement error caused by field cable resistance, delivers higher temperature measuring accuracy compared with 3‑wire version

It is widely used for high‑precision temperature monitoring of boiler drum metal wall turbine bearing and key equipment in thermal‑power‑plant closed‑loop control occasions

1000VAC galvanic isolation separates field temperature‑sensor side from DCS logic backplane suppresses ground‑loop interference and transient surge damage

It transfers field resistance variation signal to host electronic module for analog‑to‑digital conversion and backplane data transmission

No extra software configuration required after correct physical installation host module identifies personality hardware automatically

Shares hot‑swap channel diagnosis and surge suppression features from matched RTD electronic module

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

Please confirm matching host module model before purchase

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