A-167

1. Introduction

Module A-167 compares analog voltages and deri-

ves a gate signal. The state of the gate output (low/

high) depends upon which of the voltages is higher.

It is possible to compare two external voltages (+In

and -In) or an external voltage (+In or -In) with a

manually adjustable value (Offset control). Both ana-

log inputs +In and -In are equipped with an attenuator.

A LED shows the current state of the gate output.

The Gap control is used to adjust a so-called

"hysteresis". As long as this control is set to zero the

switching levels for both on and off state of the gate

signal are identical. As soon as the Gap control is

turned up the switching levels for on and off state fall

apart and a so-called hysteresis appears.

Normal and inverted gate outputs are available.

In addition the internal voltage a1*(+In) - a2*(-In) +

Offset is available at the Analog Sum socket. Conse-

quently the module can be used as subtractor and

offset generator too.
