4-20mA loop voltage consideration - Armsp0 - 08-11-2026
Although the B4 and B4M devices allow connection of a 24Vdc supply it is not clear to me that the 4-20 mA analog inputs allow use of a 24 volt loop supply. The example drawings show 12 volt supply devices connected and I am concerned that I may damage the inputs by using a 24vdc loop. Please advise what is acceptable.

yes, 24V also is ok for loop.
