This Four Channel Relay Module consists of four 5V relays each of which can be used to control 220V AC Load with a maximum current rating of 10A.

The modules operate on 5V, but the control signal can be as low as 3.3V. Meaning, the module signal pins can work both on 5V and 3.3V. The complete module’s driver section is opto-isolated for safety purposes.

Hence this 4 channel relay module is a perfect choice to be used with Arduino, ESP, Raspberry Pi, etc. to control multiple AC/DC loads. It can be used in home automation solutions, Remote IoT control and other applications where a microcontroller should drive multiple heavy loads.
