Product Brief:

1C31174G27 is Emerson Ovation HART‑enabled loop interface personality module G27 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 with HART superimposed signal.

This personality module supplies loop power for two‑wire HART smart transmitters, not only collects 4‑20mA process analog value, but also reads HART secondary data including device status, diagnostic alarm, engineering unit information.

Widely applied in thermal‑power‑plant boiler pressure, flow, liquid‑level measuring loops for intelligent instrument monitoring and predictive maintenance.

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

It transfers analog current and HART digital signal to host electronic module for conversion and backplane 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 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.
