#The Ax terminal blocks perform two functions: ADC and low voltage load control. Before measuring voltage, set the corresponding low voltage load control output to the off position. For example, if you are connecting to terminal A1, turn off A1_OUT in [[Веб-интерфейс Wiren Board | web interface]] (section Relays & FETs). | #The Ax terminal blocks perform two functions: ADC and low voltage load control.
