3) For ambient temperatures T
at the MIN error 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) For ambient temperatures T
at the MIN error current (3.6 mA).
