Supply voltage
An external power supply is necessary.
Various power supply units can be ordered from Endress+Hauser: see "Accessories" section

3) At ambient temperatures T
a
≤ -20 °C, a terminal voltage U ≥ 15 V is required to start the device with the minimum failure current (3.6 mA). The
start-up current can be configured. If the device is operated with a fixed current I ≥ 5.5 mA (HART Multidrop mode), a voltage U ≥ 10.4 V suffices
in the entire ambient temperature range.
4) A voltage U ≥ 12.5 V is required in the current simulation mode.
5) If the Bluetooth module is used, the minimum supply voltage increases by 3 V.
6) At ambient temperatures T
a
≤ -20 °C, a terminal voltage U ≥ 16 V is required to start the device with the minimum failure current (3.6 mA).
