Relay activation level can be set to HIGH or LOW. See the digrams on the board to set this.
NOTE: For complete isolation, relay power needs to go from GND to JD-VCC, with JD-VCC jumper removed. Connect Arduino to +5V and IN1 ONLY.
NOTE: The two jumper blocks near the blue terminal strip are used to set the realy activation to HIGH or LOW. See the diagrams of jumper positions on the relay board itself.
With high-current relay, AC250V 10A ; DC30V 10A
