Product Brief:

1C31177G02 is Emerson Ovation 4‑20 mA current‑output personality module G02 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 output field signals.

This personality module converts DCS internal digital control signals into stable 4‑20 mA current output, widely used for boiler water‑valve, steam‑valve and auxiliary‑equipment regulating loop control in thermal‑power‑plant sites.

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

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.
