Product Brief:

1C31189G01 is Emerson Ovation speed‑detector electronic module G01 hardware revision, it is the main electronic unit for rotating‑speed measurement, must work together with corresponding speed detector personality module.

It is plugged onto matched I/O base, receives pulse signals from proximity sensors and encoders, converts frequency signals into rotating‑speed data for DCS system.

This module is core spare part for thermal‑power‑plant turbine monitoring, supports overspeed detection and rotating‑equipment safety interlock protection.

1000VAC galvanic isolation separates field sensor 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.
