China Jfa3800 Intelligent Tachometer Price China Mechanical Tachometer Gauge China Analog Tachometer

Description:
JFA3800 series dedicated tachometer for power plant is suitable for measuring the speed of the generator set, instrument dual screen display the rpm, voltage, frequency and percentage rotate speed, some functions like as peak value memory display, wire break alarm, failure alarm,
percentage rotate speed output of 8 way relay, analog value transmit output, and RS232/485 communication interface. It can achieve centralized management of data if the standard MODBUS RTU communication protocol are used.Features:
Dual screen 5-bits digital display;
Rpm, voltage, frequency and percentage rotate speed can be displayed directly;
Wire break alarm and failure alarm, and the percentage rotate speed output of
8 way relay function can be chosen;
Analog value transmit output;
RS232 and RS485 serial interface supported by standard
MODBUS RTU communication protocol.Technical parameters:Input and outputInput signalPT:0.5-250VACAccuracyM:applicable NPN, PNP type voltage pulse,
