4 Channel Opto-Isolated Relay Board

4 Channel Opto-Isolated Relay Board

Our 4 Channel Opto-Isolated Relay Board includes four completely isolated channels for remote switching of Mains appliances, equipment and circuits. Ideal for home control and industrial applications. Each channel is controlled by a +5V TTL input and can be easily connected to an Arduino board or control system. The board provides opto isolation to prevent damage to the microcontroller from high switching voltages or short circuits in the external wiring. Schematics and operation manual included. 12V Power supply required for the board.
