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 4-6) or
 switching frequency (frequency output, see page 4-7).
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-
5).
 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 4-5).
