4.1.3 Proportional output

In the case of proportional output, a relay switches cyclically on and off

in a defined measured value range (proportional range). At the same

time, the relay switches with a:

 duration of operation that corresponds to the measured value

(pulse-width output, see page 4-7) or

 switching frequency (frequency output, see page 4-8).

Proportional outputs can be used in the following way:

 Output with one relay:

An output range is defined with a Start value and an End value. No

output takes place above and below the output range

(see page 4-6).

 Output with two relays:

An output range is defined for each relay with a Start value and an

End value. One relay outputs in the upper output range and a further

relay in the lower output range (see page 4-6).
