DC+ : input the positive pole of DC power supply2, DC- : input DC power supply cathode3. IN+ : signal input is positive4, IN- : signal input terminal negative5. NO: the relay normally opens the interface, and the relay is suspended before absorption, and is connected with COM short after absorption6. COM: relay public interface7. NC: the relay normally closes the interface, and the relay is short connected with COM before absorbing and suspended after absorbing.Key setting instructions:Power on display "-------" means to enter standby state;Press K1 for the first time (it takes more than 1 second to be effective to prevent false triggering), and it shows: p-11: K2 adjusts the main mode, K3K4 adjusts the functionPress K1 the second time, the screen will show: a001:k2 and K3 to adjust the first time A and K4 to adjust the decimal point (time unit).Press K1 for the third time, and the screen will show: b001:k2 and K3 to adjust the second time B and K4 to adjust the decimal point (time unit).Colour:greenMaterial:Electronic componentSize:6.5 x 4 x 2 cmPackage Contents:1 x Timer RelayOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
