Original Mebay Fuel Level Oil Pressure Gauge GM51HR Electric Engine Instrument

  GM51HR: An upgraded version of GM51H with an additional RS485 interface. It enables users to monitor engine parameters and configure operating parameters via PC software.  
 

2.Main Features

GM51HR: Based on the functions of GM51H, RS485 Port is added to support MODBUS Protocol.

  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.

  With maintenance prompt function, 5 kinds of maintenance countdown can be set, and the first maintenance and routine maintenance can be distinguished;

  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 coolantproof can reach IP54.

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