Original Mebay GM50H Replaced By GM50H MK3 Generator Digital Multi-function Meter Diesel Engine Monitor

Original GM50H MK3 Generator Digital Multi-function Meter Diesel Monitor Engine Control Panel

1.Summary

GM50H MK3 is one light and low price-orientated module used for demonstrating engine RPM,coolant temperature, oil temperature,oil pressure, battery voltage and Hours. The users can adjust and set the parameters by the button on the front face in order to meet the different requests. 

Besides, it uses the European-style terminals for connection which is more convenient for installation and detachment. 

2. Main Features

GM50H MK3: monitor and display RPM, Oil Pressure, coolant temperature, oil temperature, Battery voltage and Accumulation Time with Alarm function added.

  · 32bit high performance single chip microcomputer.

  · 5 screens high-light digital tube can demonstrate the parameters.

  · Various kinds of protections.

  · Input frequency is available to check RPM.

  · Variety of sensor curves' parameters is set inside.

  · Sensor curve can be self-defined by buttons.

  · It has three analog input channels of sensors, among which the oil pressure sensor is compatible with voltage signal input;

  · The parameters can be set and adjusted by the button on the front face.

  · With RS485 port, remote data monitoring can be realized by using Modbus Protocol (only GM50HR has it);

  · It has high current alarm relay, one normally open and one normally closed output, which is convenient for users to use;

  · Standard coolant-proof rubber gasket. The coolant proof can reach IP54.

  · All the connections are adapted with European connectors so that installation, connection, repair and replacement can be more easily.
