It is 6-30V 1-Channel Delay Power Relay Module with Onboard Adjustable Timing Cycle Switches with Digital LED display It is mostly used in Home Automation Delay Timer Control Switch Module Timer Controller. The Module operates at an Operating voltage range of 6-30V, also it supports micro USB 5.0V power supply.  Output capability: Can control the device within DC 30V 5A or AC 220V 5A. It can be applied to many fields as there is a wide range of application.

Operation Mode:

1. P1: Trigger signal, the relay is on “OP” time, and then disconnect; Within the “OP” time, proceed as follows:
2. P1.1: the signal is triggered again, invalid
3. P1.2: the signal is triggered again, re-clocking
4. P1.3: Signal has triggered again, the relay is disconnected, stop the clock;
5. P-2: Trigger signal, after the “CL” time is off, the “OP” time is on. When the timing is completed, the replay will be disconnected;
6. P3.1: Trigger signal, after the “OP” time is on, the “CL” time is off, then cycle the above actions. If trigger signal within the loop, the relay will be disconnected and stop the clock. The number of cycles ( “LOP “) can be set.
7. P3.2: No need to trigger the signal after powering up, the “OP” time is on, the “CL” time is off, then cycle the above actions; The number of cycles ( “LOP “) can be set.
8. P-4: Signal holding function. If the signal is triggered, timing is cleared, the relay remains on; when the signal disappears, the relay will be off when the “OP” time is over; if another signal is triggered during timing, timing will be cleared.
