This is a compact tachometer, counter, and frequency meter. It displays the RPM from a pulse-sending unit.  It has the ability to calculate and convert the pulse rate to RPM or any other unit. The gauge has an internal relay that turns on at programmed speed. In addition, it comes with a small  LED board that can be mounted on a dashboard. The LED board has tri-color high-intensity LEDs. A user can program the LED color so that it can display three different colors at a specific RPM range. This feature will help the driver to shift the gear without looking at the instrument panel.

Features:

  • Three measuring modes: tachometer (RPM), frequency meter (Hz), and counter.
  • Input power 12 - 30V DC. 
  • Supplies 12V and 5V DC to external light or buzzer.
  • Digital LED display with a range from 0 to 9999.
  • Adjustable LED brightness.
  • Support a progressive shift light with 4 assigned ranges.
  • One relay output that can be activated by high/low limit alarms.  
  • Build-in timer to record time since the meter is powered on.
  • Two multipliers which enable the user to do a simple conversion on the raw signal.
  • (Optional) 12VDC LED board can be used as a progressive shift light.    
 
Included in the package:
1 x ASL-41 Tachometer
(Optional) 1 x LED shift light (three colors: red, green, and blue)  
 

The ASL-41 tachometer and the optional LED board. 
 

Application Example:
Use the shift light (included in the product package) to indicate a different range of the measured input signal. The ASL-41 is used as a counter (P-Sn = 3). Settings: A1 = 10, A2 = 20, and A3 = 30. The color of the shift light changes as the counted number increases and passes the threshold set by A1, A2, and A3.
When the input signal is less than A1 (10)  When the input signal is between  A1 (10) and A2 (20)  When the input signal is between A2 (20) and A3 (30) When the input signal is greater than A3 (30)
