Product Brief:

1C31177G03 is Emerson Ovation HART‑enabled analog‑output 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 output with superimposed HART digital signal.

This personality module not only outputs standard 4‑20mA control current, but also carries HART digital signal, can realize parameter setting, status reading and fault diagnosis for HART intelligent valve positioners in thermal‑power‑plant regulating loops.

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

It converts DCS internal digital control signals into 4‑20mA analog output with HART modulation for field smart actuators.

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.
