HB966 intelligent dual digital frequency meter/tachometer/linear speedometer

1、 Characteristics
By setting the product number, the instrument can achieve the functions of tachometer and frequency meter
Compatible input of switch quantity and level pulse signal
External photoelectric tube, proximity switch, Hall sensor, encoder, etc
The instrument supplies 5V, 24V DC voltage or 30mA power supply to the sensor externally
Alarm value and magnification can be set arbitrarily, and all set parameters will not be lost in case of power failure
The instrument reaches the alarm set value, the relay is closed or the instrument continues to measure
Simulate current and voltage transmission output, directly convert digital quantity into analog quantity
Instrument RS485 communication (MODBUS protocol), can be connected to industrial control configuration software
