A-172

1. Introduction

Module A-172 is a Minimum/Maximum selector. It

has available four analog inputs and two analog

outputs (Minimum and Maximum).

The module permanently picks the maximum resp.

minimum voltage out of the four input signals and

outputs these voltages to the maximum resp. minimum

jack socket.

Two LEDs for each output help you keep track of the

output signals. One LED displays positive, the second

LED negative output voltages.
