Features:1. With LCD display screen, the current mode and parameters are clear at a glance.2. Support high or low level trigger, switch quantity control, suitable for most applications.3. Wide power supply voltage 6~30V, support micro USB 5.0V power supply, very convenient to use.4. Support UART data upload and parameter setting.5. One button emergency stop function (STOP button), with reverse connection protection.6. Add sleep mode, after enabling, no operation within 5 minutes, automatically turn off the LCD backlight, any buttons wakes up the screen.7. Different 0P, CL, LOP parameters can be set, these parameters are independent of each other and saved separately.8. Automatically save all parameter settings when power failure. 9. Industrial grade circuit board, with optocoupler isolation to enhance anti-interference ability.Specification:Item Type: Delay Relay ModuleWorking Voltage: 6--30VTiming Range: 0.01s-9999min continuously adjustableTrigger Signal Source: High Level Trigger (3.0V~24V), Low Level Trigger (0.0V~0.2V), Switching Quantity Control (Passive Switch)Output Capability: Can control devices within 30V 5A or within 220V 5AQuiescent Current: 15mAOperating Current: 50mAService Life: >100,000 timesWorking Temperature: -40~85CSize: 88x3.8x1.9cm / 3.15x1.5x0.75inHow to Choose Timing Range:In the OP/CL parameter modification interface, short press the STOP button to select the timing range:XXXX: Timing range is 1s~9999sXXX.X: Timing range is 0.1s 999.9sXX.XX: Timing range is 0.01s to 99.99sX.X.X.X: Timing range is 1min to 9999minParameter Setting:Parameter Description: OP: Conduction time, CL: Disconnection time, LOP: Cycle number (1-9999 times, ''----'' means infinite loop)a) Enter the setting interface by long pressing the SET button;b) First set the working mode, the working mode flashes reminder, set the working mode by short pressing the UP/DOWN button;c) Short press the SET button to select the working mode and enter the system parameter settings;d) In the system parameter setting interface, short press the SET button to switch the system parameters to be modified, short press / long press the UP / DOWN button to modify;(Note: Short press SET in P-1~p-3, P-7 mode);e) In the OP/CL parameter modification interface, press STOP to switch the timing unit (1s/0.1s/0.01s/1min);f) All parameters are set, press and hold the SET button to save the parameter settings and exit the setting interface;Working Mode Description:P1: After the signal is triggered, the relay turns on the OP time, then turns off; in the OP time, the signal is triggered again.P2: After the signal is triggered, the relay turns on the OP time and then turns off; in the OP time, the signal triggers the re-countP3: After the signal is triggered, the relay turns on the OP time and then turns off; in the OP time, the signal triggers the reset again, the relay is disconnected, and the timing is stopped.P4: After the trigger signal is given, the relay turns on the OP time after the relay is turned off, and the relay is turned off after the timing is completed;P5: Give the trigger signal, after the relay turns on the OP time, the relay turns off the CL time, then loops the above action, the signal is given again in the cycle, the relay is disconnected, the timing is stopped; the number of cycles (LOP) can be set;P6: no trigger signal is required after power-on, the relay turns on OP time, the relay turns off CL time, and the above action is cycled; the number of cycles (LOP) can be set;P7: Signal hold function If there is a trigger signal, the timing is cleared, the relay remains on; when the signal disappears, the relay is turned off after timing OP; during the timing, there is a signal and the timing is cleared;Additional Function:a) Auto sleep function: In the running interface, press or hold the STOP button to activate or deactivate the auto sleep function (L-P select on to start the sleep function, off to turn off the sleep function);b) Relay function selection: In the operation interface, the relay function is activated or deactivated by short pressing the STOP button, 'on' meets the conduction condition, the relay is normally turned on, and 'OFF' meets the conduction condition, and the relay is not turned on; 'OFF' In the state, the system flashes 'OUT';c) Parameter view: In the running interface, short press the SET button to display the current parameter settings of the system, which does not affect the normal operation of the system;d) Display content switching: In P-5 P-6 mode, switch the display content (run time/cycle number) by short pressing the DOWN button;Package List:1 x Delay Relay Module.
