Intended use
The model PSD-4-ECO pressure switch is used for the switching of circuits as a function of the measured pressure
via a PNP or NPN output signal. In addition, the pressure value can be output to appropriate read-out units as a
standardised analogue signal (4 ... 20 mA or DC 0 ... 10 V) or digital signal (IO-Link 1.1). The switching conditions can
be programmed directly at the pressure switch or by means of IO-Link 1.1 (switch and reset points, normally closed/
normally open, ...). Via the different display elements of the pressure switch, switching states and pressure values can
be read on site.
