Product Brief:

1C31194G02 is Emerson Ovation valve positioner electronic module G02 hardware revision, upgraded 3KHz LVDT excitation drive version compared with G01, must work together with corresponding valve positioner personality module.

It is plugged onto matched I/O base, outputs 23.75V AC 3KHz excitation signal for LVDT position sensor, receives position feedback signal and forms closed‑loop control for electro‑hydraulic servo valves.

This module is mainly applied for steam turbine electro‑hydraulic control system in thermal‑power‑plant, realizes high‑precision adjustment for steam valve opening, guarantees stable turbine operation.

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

Built‑in LED indicators help technicians quickly locate channel fault and module abnormality.

Supports hot‑swap operation, can be replaced online without system shutdown for convenient site maintenance.

No extra software configuration required after correct physical installation, system automatically identifies matched personality hardware.

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

Please confirm matching personality module model before purchase.

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