Product Brief:

1C31139G03 is Emerson Ovation analog output personality module G03 hardware revision works paired with 1C31132 series electronic modules

It is plugged onto I/O base together with host module defines 8‑channel hardware for 4‑20mA current analog output signals

This personality module outputs standard 4‑20mA current signal widely used for boiler control valves positioners and process actuator driving

Max 600Ω load resistance supports long‑distance field wiring for thermal‑process closed‑loop regulation

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

It converts digital control value from host electronic module into stable 4‑20mA current for field device adjustment

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

Shares hot‑swap open‑load diagnosis and surge suppression features from matched AO 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
