4.2 Power Supply
Supply voltage: + 6 V… + 30 V DC.
Max. supply current: see certificates from chapter 2.3.
For use in zone 2: see certificates from chapter 2.3.
The sensors of the A5S1...-n series may only be operated in hazardous area zone 2.
Current consumption: approx. 15 mA (one channel sensor) resp. 25 mA (two channel sensor),
plus load (can increase up to 60 mA with long transmission length and high signal frequency).
If powe
r supply isn’t provi ded by a BRAUN device, a PELV resp. SELV power supply has to be
used.
