Features:_x000D_ _x000D_ To achieve fast high frequency turn-on and off circuit, an unlimited number of switching times. _x000D_ No noise was made during turning on/off, no spark, and no electromagnetic interference. _x000D_ Compared to normal electromagnetic relay modules, it has a longer service life. _x000D_ Dual-MOS in parallel active output, lower inner resistance, larger current, strong power; at room temperature, operating current is up to 15A, power up to 400W, that can be used for most equipment. _x000D_ Wide voltage input from 5V to 36V, normally used for controlling DC motors, lights, LED strips, micro-pumps, solenoid valves, etc., very convenient. _x000D_ It has an emergency stop function ("STOP" button) and reverse input protection. _x000D_ Automatically enter sleep mode and shut off display if no operation in 5 minutes, and will be wake up by pressing any button. _x000D_ You can set different OP, CL, LOP parameters, which are independent of each other, and are saved separately; _x000D_ All parameter settings will be saved automatically if there is a power failure. _x000D_ _x000D_ Specifications: _x000D_ Voltage: DC 5V~36V. _x000D_ Trigger Signal Source: High voltage level trigger (3.0V~24V), signal ground and system ground are not on common ground to improve the system's anti-jamming capability (you can also connect them on common ground). _x000D_ Output Capacity: DC 5V~36V, at room temperature, continuous current is 15A, power 400W. With enhanced heat dissipation, the current can be up to 30A. _x000D_ Quiescent Current: 20mA _x000D_ Operating Current: 50mA _x000D_ Working Temperature: -40~85 _x000D_ Clocking (Time Delay) Range: 0.1seconds to 999minutes _x000D_ Size: 60*34*12mm / 2.36*1.33*0.47" _x000D_ _x000D_ Instruction: _x000D_ Operating Mode: _x000D_ P1: trigger signal, the relay is on "OP" time, and then disconnect; in the "OP" time, as follows: _x000D_ P1.1: signal is triggered again, invalid _x000D_ P1.2: signal is triggered again, the clocking is reset _x000D_ P1.3: Signal is trigger again reset, relay off, and stop the clocking; _x000D_ P-2: trigger signal, the relay off "CL" of time, the relay on "OP" time, and then disconnect relay after clocking; _x000D_ P3.1: trigger signal, the relay is turned on after the "OP" time, the relay off "CL" time, then the operation cycles; if trigger signal again during the cycle, the relay off, stop clocking; the number of cycles times ( "LOP ") can be set. _x000D_ P3.2: without triggering signal after power on, the relay is on "OP" time, the relay off "CL" time, then the operation cycles; the number of cycles times ( "LOP ") can be set. _x000D_ P-4: signal holding function. If there is trigger signal, clocking is reset, the relay remains on; when the signal disappears, after clocking "OP" time, the relay is off; if another signal is triggered during clocking, clocking will be reset. _x000D_ _x000D_ _x000D_ How to Set Clocking Range: _x000D_ After setting the parameter value at mode selection, press "STOP" button to set the clocking range; _x000D_ XXX. The last decimal point lights up, range: 1 second to 999 seconds. _x000D_ XX. X The second last decimal point lights up, range: 0.1 seconds to 99.9 seconds _x000D_ X. X. X. all 3 decimal points light up, range: 1 minute to 999 minutes. _x000D_ For example, if you want to set "OP" as 3.2 seconds, light up the second last decimal point, and set digit display as 03.2 _x000D_ _x000D_ Parameter Description: "OP" - on time, "CL" - off time, "LOP" - number of cycle times (1-999 times, "---" represents infinite loop). _x000D_ These parameters are independent of each other, but are shared by each mode. For example, in P1.1 mode, set the on-time "OP" is 5 seconds, if you switch to P1.2 mode, its "OP" will also be 5 seconds. _x000D_ In the main interface (display 000), press "SET" button will display "OP" ( "CL", "LOP") and the corresponding time XXX; _x000D_ If the mode (such as the mode P1.1, P1.2, P1.3) only has "OP" time, press the "SET" key to display only the "OP" and the corresponding time; _x000D_ Some models (such as the mode P3.1, P3.2) have parameters "OP", "CL", "LOP", press "SET" button will display "OP" and the corresponding time, "CL" and the corresponding time, "LOP" and the corresponding number of times; _x000D_ After setting mode, in the main interface press "SET" key to see information about the parameters of the current mode, very convenient. _x000D_ _x000D_ How to Set Parameters: _x000D_ 1. First, read the instructions to determine the required operating mode. _x000D_ 2. The module is powered up, the display at the current work mode (P1.1 default mode), then enter the main interface; press and hold "SET" button for 2 seconds to enter mode selection interface; then press "UP", "DOWN" button to select the mode (P1.1 ~ P-4). _x000D_ 3.
