 - For resistive or slightly inductive loads (AC1 classification), Arduino Opta's *Rated Load* is 2500 VA.
 - For small electromagnetic loads (> 72 VA) (AC15 classification) like power contactors, magnetic solenoid valves, electromagnets and AC single-phase supplies, Arduino Opta's *Rated Load* is 500 VA. This value assumes a peak inrush current of approximately 10 times the rated current and keeping it within the maximum peak current.

 In the case of the minimum switching load parameters, the minimum values of power, voltage and current that the relays can reliably switch, are 300 mW/ 5V / 5mA. This implies that with 5V the current must be at least 60mA, with 24V, it must be at least 12.5mA, and with 5mA the voltage must be at least 60V.
