Power supply
The permissible power supply depends on the corresponding value of the output signal.
Output signal
4 ... 20 mA
DC 0 ... 10 V
DC 0 ... 5 V
DC 1 ... 5 V
DC 0.5 ... 4.5 V

The power supply for the pressure transmitter must be made via an energy-limited electrical circuit in accordance with section 9.3 of UL/
EN/IEC 61010-1, or an LPS to UL/EN/IEC 60950-1, or class 2 in accordance with UL1310/UL1585 (NEC or CEC). The power supply must
be suitable for operation above 2,000 m should the pressure transmitter be used at this altitude.
