Current consumption
HART
Nominal current 3.6 to 22 mA the start-up current for multidrop mode can be parametrized
(is set to 3.6 mA on delivery)
Breakdown signal (NAMUR NE43) adjustable: 3.59 to 22.5 mA
Power supply failure
• Configuration is retained in the HistoROM (EEPROM).
• Error messages (incl. value of operated hours counter) are stored.
Potential equalization
No special measures for potential equalization are required.
If the device is designed for hazardous areas, observe the information in the documentation
"Safety Instructions" (XA).
