Electronic Pressure Sensor 34D Operation manual Function The unit displays the current system pressure. It generates output signals according to the operating mode and the parameter setting. It moreover provides the process data via IO-Link. The unit is laid out for fully bidirectional communication. So, the following options are possible: o Remote display: reading and display of the current system pressure.
Electronic Pressure Sensor 34D Operation manual 4.3 Analogue function OUT2 is an analogue output: [ou2] defines whether the set measuring range is provided as 4...20 mA ([ou2] = [I]) or as 0...10 V ([ou2] = [U]) 34D-xxxxx-DA1-AA: Analogue signal 4...20 mA / 0...10 V corresponds to the measuring range 0...10 bar. Negative pressure values cannot be represented via the analogue output for the indicated units.
Electronic Pressure Sensor 34D Operation manual 4.4 IO-Link General Information This unit has an IO-Link communication interface which requires an IO-Link-capable module (IO- Link master) for operation. The IO-Link interface enables direct access to the process and diagnostic data and provides the possibility to set the parameters of the unit during operation.
