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).
