Original GM51H Digital Display Multifunctional Controller for Diesel Generators

Original GM51H Digital Display Multifunctional Controller for Diesel Generators

1.Summary

GM51H is one light and low price-orientated module used for demonstrating engine RPM,coolant temperature, fuel level,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

There are two models for GM51H series Meter:

GM51H: monitor and display RPM, Oil Pressure, coolant temperature, Fuel level, Battery voltage and Accumulation Time with Alarm function added.

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.
