The Tach Signal Converter (Tach2) converts SIM P-Lead signals to negative –going signals compatible with the Horizon P-1000 digital tachometer input and to a positive-going 0-5V square wave signal compatible with electronic tachometers that rely on a signal from a magnetic pickup inserted into a magneto.

Tach 2 can accept one or two SIM P-Leads as input, converts and conditions the signals and outputs them to corresponding output terminals. The Tach2 must be installed in the aircraft cabin and secured to the airframe with screws and nuts. The Tach2 power input from the aircraft bus may range from 8.5VDC to + 30VDC without damage. The Tach2 consumes less than 0.25A of power.
