Feature:1. The conduction and cutting process does not produce noise, sparks or electromagnetic interference.2. Compared with electromagnetic relay products, the service life is longer.3. This product can realize fast switching of the circuit, and the number of switching is unlimited.4. The module is featured with optocoupler and insulation, greater anti-interference ability, industrial grade board.5. Most equipment can use this product as it is very convenient; The interface is clear and simple, powerful, easy to understand, and almost meets all your needs.Specification:Item Type: Timer delay switch circuit board.Material: PcbSize: Circuit board Approx. 60 x 34mm / 2.4 x 1.3inProduct Parameters:1: Working Voltage: 5-36V.2: Trigger Signal: (3,0 V-24V), with optocoupler isolation, can improve the anti-interference ability of the system (customers can also shorten the public ground).3: Output Power: DC 5V-36V, at room temperature, DC 15A, power 400W! Improve heat dissipation conditions, the maximum current reaches 30A.4: Quiescent Current: 20mA; working current: 50ma5: Working Temperature: -40-856: Optocoupler and insulation, greater anti-interference ability, industrial grade board.Note:The module has an active output, the output voltage is equal to the input voltage.2'DC+' and'charge+' are internal short circuits of the magnetic poles, but'DC-' and'charge-' cannot be shortened during use, otherwise the charge cannot be switched, and the equivalent charge carries electricity.The input voltage is large (5 ~ 36V), most of the equipment can be used, very convenient;The interface is clear and simple, powerful, easy to understand, and almost meets all your needs;Emergency stop function ("stop" key); under reverse polarity protection, reverse polarity will not burn the product.Increase the pause mode, if the mode is activated, there is no operation within 5 minutes, and then automatically turn off the monitor, any button can be activated;You can set different OP, CL, LOP parameters, these parameters are independent and automatically saved;After the module is closed, all parameter settings will not be lost.Way of working:P1: Trigger signal, the relay is at "OP" time and then disconnected; at "OP" time, as follows:P1.1: The signal is activated again and is invalid.P1.2: The signal is activated again and the clock restartsP1.3: The signal is activated again, the relay is closed, and the clock is stopped;P -2: Trigger signal, the relay is closed for "CL" time, the relay is for "OP" time, then disconnect the relayP3.1: Trigger signal, the relay starts after the "OP" time, the relay closes the time "CL", and then runs the cycle. If the trigger signal period, the relay is closed and the clock is stopped; the number of cycles ("LOP") can be set.P3.2: No trigger signal, the relay enters the time "OP", the relay closes the time "CL", has been riding a bicycle; you can set the frequency cycle ("LOP");P-4: Signal function If the synchronization of the trigger signal is deleted, the relay remains on; when the signal disappears, the relay is after the "OP" synchronization time; if there are other signals during the synchronization process, the timing is clear;Package List:1 x Relay Module
