ZNZS2-6E1R tachometer/line speed meter, NPN pulse signal input, 1 set of relays, overspeed or low speed alarm output, electronic ratio adjustment and other functions, power supply AC/DC100-250V, output auxiliary power supply DC12V, for sensor use, and tachometer The matching sensors are: proximity switch, Hall switch, encoder, photoelectric switch.
Smart tachometer can display the speed（That is how many revolutions per minute）, You can also display the line speed（How many meters, centimeters, millimeters per minute）, The ratio setting is somewhat different, as described below.
Two speed modes: high-speed mode and low-speed mode, the parameters of high-speed mode indicate:（SP----H,）With smoothing filtering, the parameters of low-speed mode indicate:（SP----L）There is no smoothing filter, and there is a password protection function.
Dimensions: 48*96*75MM (width * length * depth), opening size: 45*92MM（Width*length）.
The tachometer defaults to 220V power supply, and 24VDC is required to take a message
Supporting sensor picture display:
Tachometer + proximity switch（Speed ??range 20-600 rpm）, Select low speed mode（SP----L）
Tachometer + encoder（0.1 rpm-5500 rpm）（The number of pulses is different, the speed is different）
High-speed kit: tachometer + optical fiber (slow reflection) can measure 40,000 revolutions
Linear Speedometer Tachometer + Encoder + Meter Wheel Bracket Complete
Tachometer + Hall switch（20-3000 revolutions）
New LCD speedometer

Linear speed meter + meter wheel:
Tachometer + Hall switch installation diagram:
Install a magnet on the Hall switch, if it is a proximity switch, install an iron block or screw
Tachometer + encoder installation diagram:
Linear speed ratio setting: If 10 points are sensed, the circumference of the roller is 30CM, and the linear speed ratio=60/10*30=180 setting（P-180.0）
Dears! First explain, if you need a DC24V power tachometer, talk to the customer service, if you don’t explain, we will send a 220V tachometer by default!

Physical picture of tachometer DC 12V wiring:
Connect the DC 12V power supply, the positive end is connected to the No. 17 terminal, and the negative end is the No. 14 terminal, and the connection method is the same as the sensor power line.
