PiRelay v2 Relay Shield for Raspberry Pi
The PiRelay V2 has the ability to handle four appliances and loads up to 250V AC/7 A, 30V DC/10 A, allowing it to control high voltage/current devices. It enables the user to improve the appliance's intelligence. It includes a "Optocoupler," which allows an electrical signal to be transmitted between two separated circuits using light energy. The usage of an optocoupler allows the user to avoid excessive voltages in one portion of the circuit from influencing the other, ensuring the system's safety.
