4-Relay Shield

4-Relay Shield has 4 optocoupled inputs for voltage signals 12VDC without the problem of burning the Arduino and Raspberry Pi, ideal for water level sensors, opening doors and windows.

Arduino Shield 4-Relay uses the pin D4, D5, D6 and D7 for optocoupled inputs, A0, A1, A2 and A3 as outputs to actuate the relays through Arduino. To work with Raspberry optocoupled inputs are connected to the GPIO 12, 16, 18 and 22 pin, to actuate relays GPIO 7, 11, 13 and 15 are used.

Relay specifications:

Max 24VDC 10A 230VAC 10A
