Original Mebay GM51HR Digital Engine Meter Tachometer Voltmeter Diesel Generator PMEP

Original Mebay GM51HR Digital Engine Meter Tachometer Voltmeter Diesel Generator PMEP 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. 5.Parameters OptionsParameters Working voltageDC8V----36V Continuous Power consumptionStandby：24V：MAX 1W Working：24V：MAX 1.5W AC Voltage Input1P2W 50VAC-280VAC（45～70Hz） Rotate speed sensor Frequency50-10000Hz(AC3～65V) MAX Accumulating Time99999.9Hours（Min storage time:6min） Relay Output5AMP Non-contact normal open & normal close output Working condition-25-65℃ Storage condition-40-85℃ Protection LevelIP54：when coolantproof rubber gasket is added between meter and its panel Insulation strengthApply AC2.2kV voltage between high voltage terminal and low voltage terminal; The leakage current is not more than 3mA within 1min.
