1) Feature 020 of the product structure: option A
2) Feature 010 of the product structure
3) For ambient temperatures T
(3,6 mA). For ambient temperatures T
current (3,6 mA). The startup current can be parametrized. If the device is operated with a fixed current I ≥ 4,5 mA (HART multidrop mode), a
voltage of U ≥ 11,5 V is sufficient throughout the entire range of ambient temperatures.
4) If the Bluetooth modem is used, the minimum supply voltage increases by 2 V.
5) For ambient temperatures T
(3.6 mA).
