6 Function
The sensor converts pneumatic pressure values (relative pressure) into electrical
signals, which can be used for control or regulating functions. Measurements are
carried out using a piezoresistive sensor element with a following electronic eval-
uation unit. Connection to the higher-level system is provided by 1 or 2 switching
outputs, an analogue output and/or an IO-Link interface. The switching outputs
can be configured for monitoring of a threshold value, a pressure range or a differ-
ential pressure. For each output, PNP or NPN and normally open (NO) or normally
closed (NC) can optionally be set. Through the IO-Link interface, process values
can be read out and parameters changed and transmitted to additional devices.

6.2.3 Auto difference monitoring d_|¯|_
This function permits monitoring of a pressure value for constancy. The applied
pressure is constant in the range between [SP.Lo] and [SP.Hi], so the reference
pressure PRef is automatically determined. The result is a switching operation at

WARNING!
Risk of injury due to electric shock.
• For the electric power supply, use only PELV circuits that ensure a reliable
electric disconnection from the mains network.
• Observe IEC60204-1/EN60204-1.

Long signal lines reduce the resistance to interference.
• Adhere to the maximum permissible cable length of 30 m (20 m for IO-Link).
