3) At ambient temperatures T
a
≤ -30 °C, a terminal voltage U ≥ 14 V is required to start the device with the
minimum failure current (3.6 mA). At ambient temperatures T
a
> 60 °C, a terminal voltage U ≥ 12 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 ≥ 4.5 mA (HART Multidrop mode), a voltage U ≥ 11.5 V suffices in the entire
ambient temperature range.
4) If the Bluetooth module is used, the minimum supply voltage increases by 2 V.
5) At ambient temperatures T
a
≤ -30 °C, a terminal voltage U ≥ 16 V is required to start the device with the
minimum failure current (3.6 mA).
