Turn up to eight devices on and off at the same time from your Arduino, Raspberry Pi, or other microcontroller. This relay module from Whadda is directly controlled via the digital outputs of your board, with no extra driver electronics needed.
Each input is separated from the relay section by opto-isolation. This way, your microcontroller stays protected from voltage spikes and interference from the switched side. Handy when switching mains voltage, motors, lighting, or pumps. A status LED per channel immediately shows if the relay is engaged, making testing your circuit a lot clearer.
The relays switch up to 250 VAC / 10 A or 30 VDC / 10 A (non-inductive). The module operates at 5 V and accepts control voltages from 5 to 12 VDC, allowing it to work with both 5V and 12V logic.
