1) Feature 020 of the product structure: option A
2) Feature 010 of the product structure
3) For ambient temperatures T
mA). For ambient temperatures T
(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) For ambient temperatures T
