Product Brief:

1C31189G03 is Emerson Ovation speed‑detector personality module G03 hardware revision, must be paired with 1C31189G01 speed detector electronic module.

It is plugged onto I/O base together with host electronic module, provides signal conditioning interface for magnetic pickup and proximity speed sensors.

This personality module converts weak pulse signals from turbine speed sensors into stable signals for electronic module processing, widely used for steam turbine rotating‑speed measurement and overspeed protection in thermal‑power‑plant.

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

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

Shares hot‑swap, channel diagnosis and surge‑suppression features from matched speed detector electronic module.

This is EOL discontinued spare part widely used for maintenance and renovation of thermal power plant Ovation DCS system.

Please confirm matching 1C31189G01 host module model before purchase.

Strict ESD anti‑static protection shall be followed during installation and replacement.
