2. Hardware Description

2.1. Description

This device is suitable for monitoring the speed of two DC fans.

The tachometer signal of the fans is monitored and evaluated. If

a minimum speed is not reached, e.g. due to dirt or motor

standstill, an externally evaluable signal is output. In addition, the

fan status can be signalled via an LED output.
The module also generates a motor speed voltage. This can be

switched from 1V ... 8V with a potentiometer and is used to set

the maximum rotational speed of both fans.
