                  As long as you write ARDUIUO code(sketch),You can use it to achieve a variety of delay timer function,such as:
                  Motor forward and reverse,Timing on,Timing off,Power-up delay,Trigger delay,Infinite loop delay,A finite number of cyclic delays,Power sequencer,And so on.
                  Note: IO22C04 can not work independently, must be under the control of the Pro mini board to work,If you do not have a Pro mini board, purchase it separately or purchase a kit with Pro mini.
                  Package Included:
                  1 x Multi-Function Delay Relay PLC Power Timing Device
