Supply voltage:
24 V±1 V (when HART communication resistance is off. Maximum load current: 24 mA)
24 V±6 V (when HART communication resistance is on. Maximum load current: 20 mA)
At the ambient temperature (Ta) of +23°C±5°C.
For the accuracies of other ambient temperature ranges (Ta<18°C, Ta>28°C), add the temperature coefficient 0.005% of Range/°C.
