Product overview
systems via switching outputs, a volume switching pulse, an analogue output or an IO-Link interface.
Depending on the configuration, the switching outputs monitor a threshold value or a signal range.
The outputs can be set as PNP or NPN and normally open (NO) or normally closed (NC). The analogue
output can be operated either as a voltage output or as a current output. Through the IO-Link
interface, process values can be read out and parameters changed and transmitted to additional
devices. If the flow rate is integrated, a volume signal or mass signal can be calculated and output via
a pulse output and an accumulated measured value via IO-Link.
