PiRelay 8 with LCD Display with LCD display

The PiRelay 8 is an amazing relay expansion board that can control up to 8 appliances or devices. It features photo - coupling isolation, handling loads up to 250V AC/7 A and 30V DC/10 A, with a 3.3 V trigger voltage. This allows you to safely manage high - voltage or high - current devices. The board has ample space for a 4.3' LCD, making device operation a breeze. A great feature is the 5 V/2A USB power port, which directly powers the Raspberry Pi. It comes with 8 high - quality relays capable of withstanding the specified loads. An Optocoupler EL357NC in the 8 channels acts as a photo - coupling isolator for safe communication.

Using the PiRelay 8 is easy. First, connect your appliances or devices to the relay expansion board, making sure to follow the voltage and current limits. The 4.3' LCD display on the board makes it simple to operate. Just power it up using the 5 V/2A USB power port, which also powers the Raspberry Pi. When you want to control your devices, use the appropriate trigger voltage of 3.3 V. As for maintenance, keep the board clean and free from dust. Check the relays regularly for any signs of wear. Make sure the photo - coupling isolator (Optocoupler EL357NC) is working properly for safe communication. Always be careful when dealing with high - voltage or high - current devices. Do not exceed the specified load limits to avoid damage to the board and ensure your safety.
