Raspberry Pi Relay Board Description

The Raspberry Pi Relay Board is a powerful extension for your Raspberry Pi . It allows you to control devices with high voltage or current. With this board you can transform simple household appliances into smart devices. The board is equipped with a standard 40PIN GPIO expansion header that is compatible with the Raspberry Pi series. It features high-quality relays that can handle loads up to 5A at 250V AC or 5A at 30V DC. Thanks to the photocoupler isolation, the board is protected from interference from high voltages. It also has LED indicators for the status of the relays and a jumper for relay control. This allows you to control the relays with custom pins, not just the standard ones. The board comes with development resources. Including examples in wiringPi, WebioPi, shell, python and bcm2835. Each of the three screw terminals on the board has three pins for connecting external circuits. These terminals are low active, meaning that when the Raspberry Pi outputs a low level, the corresponding LED will light up and the relays will switch the external circuits on or off.
