Power supply

Order characteristic for
"Output"
Option C
1) When using only one output: use output 1.
An external power supply is required for each output.
Order characteristic for
"Output"
Option C
* External supply voltage of the power supply unit with load (® ä 26)
• Operation with output 1: 65 to 660 mW
• Operation with output 1 and 2: 130 to 1 320 mW
3.6 to 22 mA
If the option Defined value is selected in the Failure mode parameter (® ä 96):
3.59 to 22.5 mA
• Totalizers stop at the last value measured.
• Configuration is retained in the HistoROM.
• Error messages (incl. total operated hours) are stored.
(® ä 24)
No special measures for potential equalization are required.
