Note! Not for professional use. Do not use to control mains-voltage equipment. Only for voltages below 50VAC/DC.

You can control the single relay on the module. The input is equipped with an optocoupler which provides better protection. All connections are screw terminal blocks. Status LEDs indicate the relay state.
