System 182-XT-4 Outputs Pulse width output The output via the pulse width is used, e.g. for controlling valves. Pulse-width regulation changes the duration of operation (ton) of the output signal. Depending on the position of the measured value in the proportional range, the relay is operated for a longer or shorter period.

Outputs System 182-XT-4 Frequency output Switching frequency output is used, e.g. for controlling dosing pumps. In contrast to the pulse-width output, the pulse width is not modulated with the frequency output but the switching frequency of the output signal. Depending on the position of the measured value in the proportional range, the relay is switched more often or less often.
