BAOCHAI GM50H Generator Controller

GM50H MKII Engine Digital Display

Module Overview

The GM50H MKII is a lightweight, low-cost module for measuring and displaying engine RPM, water temperature, oil temperature, oil pressure, battery voltage, and engine runtime totalization. Parameters can be adjusted and set via pushbuttons to meet the needs of different applications. In addition, European style terminal wiring is adopted to facilitate the installation, removal and replacement of the module.

The GM50H MKII series instruments are available in five models:

GM50H MKII: Collecting engine parameters through resistive sensors, with alarm protection function, and modifying parameters through pushbuttons;

GM50HR: on the basis of GM50H, add RS485 interface, can monitor engine parameters and set running parameters through PC software;

GM50C: read engine parameters through CAN interface and built-in J1939 protocol, with alarm protection function, and modify parameters by pressing keys;

GM50CR: add RS485 interface on the basis of GM50C, it can monitor engine parameters and set running parameters through PC software, and can connect with remote copy meter to view parameters;

GM50RE: remote copy instrument, used to connect with GM50H series instrument with RS485 interface, to realize remote parameter monitoring, a copy instrument to monitor a host.

One secondary instrument can monitor one main unit. Function Characteristics
