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 6-9) or

 switching frequency (frequency output, see page 6-10).

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 6-8).

 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 6-8).
