Hi, I am looking at doing a small project with work. They would like a Tachometer display when a Pot is turned connected to a M171PWM contoller (M171 PWM Power control 9 - 28 V/DC, max. 10 A)
Basically, when the pot is turned, it will range from 700RPM (low idle) to 2300RPM (high idle).
What would I require to achieve this ? Thanks so much in advance. Ian.
