1. Introduction

1.1. Foreword

First of all, we would like to congratulate you to the purchase of a

high quality DEDITEC product.

Our products are being developed by our engineers according to

quality requirements of high standard. Already during design and

development we take care that our products have -besides

quality- a long availability and an optimal flexibility.

Modular design

The modular design of our products reduces the time and the

cost of development. Therefor we can offer you high quality

products at a competitive price.

We ensure a long delivery availability!

If semiconductors are no longer available, we can react faster.

With us, usually only modules have to be redesigned and not the

entire product. This increases the delivery availability.

1.2. Customer satisfaction

Our philosophy: a content customer will come again. Therefor

customer satisfaction is in first place for us.

If by any chance, you are not content with the performance of our

product, please contact us by phone or mail immediately.

We take care of the problem!

customers. Therefor we are thankful for comments and

suggestions.

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.
