Power supply voltage of the controller must not be lower than voltage of the connected load. Connect "+" of the load to "+" of the power source, and "-" to Ax or Dx terminals. If several channels are used, and their total current exceeds 5 A, connect several GND terminals to "-" of the power source. Voltage spikes occur when the device controls an inductive load (relay). In order to protect the controller from overload, it is equipped with built-in protective diodes. No external protective elements are necessary.
