Product Brief:
1C31174G03 is Emerson Ovation current‑loop interface personality module G03 hardware revision, works paired with Ovation analog I/O electronic main module.
It is plugged onto I/O base together with host module, defines hardware interface for 4‑20 mA analog input and 4‑20 mA analog output field signals.
This personality module supplies loop power for two‑wire field transmitters, widely used for pressure, flow, liquid‑level measuring loop and regulating valve control in thermal‑power‑plant sites.
1000VAC galvanic isolation separates field instrument side from DCS logic backplane suppresses ground‑loop interference and transient surge damage.
It transfers field 4‑20 mA current signals to host electronic module for A/D conversion, and converts internal digital signals into 4‑20 mA analog output to drive field positioners and I/P converters.
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 analog I/O electronics 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.
