3.5 Voltage supply
Power supply
The power supply depends on the selected output signal.
■ 4 ... 20 mA: DC 8 ... 30 V
■ DC 0.5 ... 4.5 V: DC 8 ... 30 V
■ DC 0 ... 5 V: DC 8 ... 30 V
■ DC 1 ... 5 V: DC 8 ... 30 V
■ DC 0 ... 10 V: DC 14 ... 30 V
■ DC 0.5 ... 4.5 V (ratiometric): DC 4.5 ... 5 V
The power supply for the pressure transmitter must be made via an energy-limited electrical circuit
in accordance with section 9.4 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.
