hello

I have seen somewhere in calculating the current which used by SB 1223 2*24 vdc input/2*24 vdc output (this signal board of s7 1200) :

50 mA ( for back plane bus )+ 2 (input)* 4 mA = 58mA

so what about output? they are not consumming power ( so current )?

thank you for your advice

hi,

it depends on your actuator, how much current it needs. It can be up to 0.1A per Output.

hi hamed,

when you know what actuator you are going to connect there, you need to use the value from the actuator. If you don´t know what kind of actuator the output is feeding, you can take the maximum value to be safe.
