????????? ???? Smart DC 6V~30V Trigger Delay On/Off Cycle Timer Relay Switch Module w/Digit LED Display Micro USB 5V

Specifications: Trigger Signal Source: High voltage level trigger(3.0V~24V), signal ground and system ground are not connected to improve system anti-interference ability(or you can connect them). Load Capacity: DC 30V 5A, AC 220V 5A Quiescent Current: 20mA Operating Current: 50mA Timing Range: 0.1seconds to 999 minutes(continuously adjustable) Instruction: Operation Mode: P1: After triggering signal, switch is connected for "OP" time, then disconnected; within the "OP" time: P1.1: if trigger signal again, it is invalid. P1.2: if trigger signal again, restart timing. P1.3: if trigger signal again, switch is disconnected, stop timing. P-2: After triggering signal, switch is disconnected for "CL" time, then switch is connected for "OP" time, and disconnect after timing. P3.1: After triggering signal, switch is connected for "OP" time, then switch is disconnected for "CL" time, and enter loop. If trigger signal during loop, switch is disconnected and stop timing. The loop times (LOP) can be set. P3.2: After power on, no need trigger signal, switch will be connected for "OP" time, then disconnected for "CL" time, and enter loop. The loop times (LOP) can be set P-4: Signal holding function. If there is trigger signal, timing will be reset, switch remains connected; when the signal disappears, it will disconnect after "OP" time. During timing, if there is a signal, timing will be reset. OP: Connect time. CL: Disconnect time. LOP: Loop times(1~999, "---" indicates infinite times) All above parameters are independent from each other, but all modes use the same parameters. For example, if set OP time as 5 seconds in P1.1, then change to P1.2, then the OP time in P1.2 will also be 5 seconds. Package Includes: 1 x Timer Switch Module
