Features Specification Description: Operating current: 5V, forward 4mA, reverse: 36mA; 12V, forward 6mA, reverse: 44mA Load current: Max 2A Forward max time: 5000 seconds, 0.1 seconds step Reverse max time: 5000 seconds, 0.1 seconds step Size: 54*22*15mm / 2.12*0.87*0.59in Weight: Approx. 15g How to use: VIN connected to the positive of power supply , GND connected to the negative of power supply; P+ connected to the positive of motor power supply, P- connected to the negative of motor power supply; M + & M- connected to both ends of the motor After power, D1 flashes for 3 times, D2 off, M+ output positive, M- output negative, motor forward; After a time delay T1, D2 on, M+ output negative, M- output positive, motor reversal; After a time delay T2, D2 off, M+ output positive, M- output negative, motor forward; And so on. T1: motor forward delay time, default 0.1-5000 seconds adjustable (step 0.1 seconds) T2: motor reverse delay time, default 0.1-5000 seconds adjustable (step 0.1 seconds) By "Time multiple selection" setting, the maximum delay is up to 40,000 seconds How to Set Up: After power on, D1 3 blinks, enter the "work mode" D2 on Reversal, D2 off Forward Press and hold the key for 2 seconds, D1 on, enter the "setup mode" D2 off, It's forward "setup mode" In forward "setup mode", continuously trigger KEY twice, D1 off, enter "Standby timer mode" In the "Standby timer mode" , trigger KEY to start timing(enter "Timing Mode") D1 flashing means it is timing("Timing Mode") Trigger KEY again to stop the clock(exit "Timing Mode") D1 flashing time is forward time(T1) Press and hold the Key for 2 seconds, D2 on, enter the Reverse "setup mode" In Reverse "setup mode", continuously trigger key twice, D1 off, enter "Standby timer mode" In the "Standby timer mode", trigger KEY start timing(enter "Timing Mode") D1 flashing means it is timing("Timing Mode") Trigger KEY again to stop the clock(exit "Timing Mode") D1 flashing time is Reverse time(T2) So far, forward time(T1) and reverse time(T2) is set up Re-power in "work mode" Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
