Product Brief:
1C31194G01 is Emerson Ovation valve positioner electronic module G01 hardware revision, dedicated for pneumatic regulating valve closed‑loop position control, must work together with corresponding valve positioner personality module.
It is plugged onto matched I/O base, receives 4‑20mA control signal from DCS controller, outputs proportional pneumatic pressure to drive field pneumatic actuator, meanwhile collects valve position feedback signal to form closed‑loop regulation.
This module is widely used for boiler water supply, steam temperature and steam pressure regulating loops in thermal‑power‑plant, improves valve positioning precision and process control stability.
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.
