Product Description

DC 5-30V Digital Time Delay Relay Dual LED Display Timer Control Switch Adjustable Timing Relay Time Delay Switch with Micro USB Description: The main parameters: Product Name: Delay Relay Module Product Number :DK-LJ02 Working voltage: DC 6V-30V or 5V Micro USB Control current: 10A (Max) Quiescent current: 15mA Working current: 50mA Working temperature: -40~85° Applicable battery: battery, lithium battery Size/weight: length 80 * width 38 * height 23mm / 35g Trigger signal source: high level trigger (3.0V~24V) Low level trigger (0.0V~0.2V) Features: 1. LCD display 2. Support high and low level trigger 3. Emergency stop function 4. Sleep mode, wake up with any button 5. Automatically save parameters de description 6. Support UART settings 7. Independent of parameters 8. Continuously adjustable from 0.01 second to 9999 minutes; 9. Optocoupler isolation. Enhanced anti-interference ability Working Mode Description: Op: opening time; CL: closing time; LP: Number of cycles. The range is 1-9999 times.- ：-means infifinite loop. P1: The relay will hold the time OP after obtaining the trigger signal, and then the relay will be OFF; if the trigger signal is obtained again within the delay time OP, the input signal is invalid. P2: The relay will hold the time OP after obtaining the trigger signal, and then the relay will be OFF; if the trigger signal is obtained again within the delay time OP, the module will restart the delay. P3: The relay will hold the time OP after obtaining the trigger signal, and then the relay will be OFF; if the trigger signal is obtained again within the delay time OP, the module will reset and stop timing. P4: The relay will remain OFF at time CL after obtaining the trigger signal, then the relay will remain ON at time OP, and then the relay will be OFF. P5: The relay will hold the time OP after obtaining the trigger signal, and then the relay will remain OFF for the hold time CL, and then perform the above operations cyclically. The module will reset and stop timing. If the trigger signal is obtained again during the cycle, the relay will be disconnected. LOP) can be set. P6: After the relay is powered on, it will remain in the on state at time OP without a trigger signal, and then the relay will remain in the off state at time CL, and then perform the above operations cyclically.The number of cycles (LOP) can be set. P7: Signal hold function. When the trigger signal is kept, the reset delay time and the relay remain ON. When the signal disappears, the relay remains OFF. When the trigger signal is obtained again during the timing, the delay time is reset. Timing Range: Continuously adjustable from 0.01 second to 9999 minutes. In the OP / CL parameter modifification interface (flflashing), short press the "STOP" button to enter the setting interface and select the timing range. Please pay attention to the position of the decimal point when you press the button. Display "XXXX", no decimal point, timing range is 1 second to 9999 seconds. "XXX.X" is displayed. The decimal point is the second to last, and the timing range is 0.1 second to 999.9 seconds. "XX.XX" is displayed, the decimal point is third to last, and the timing range is 0.01 second to 99.99 seconds."X.X.X.X" is displayed. The decimal point is fully lit, and the timing range is 1 minute to 9999 minutes. For example, if you want to set OP to 3.2 seconds and move the decimal point to the second to last position,the LCD will display "003.2". Setting Parameters: 1. Long press the "SET" button to enter the setting parameter menu. 2. The working mode will flflash fifirst, set the working mode. Short press the UP / DOWN button to set the working mode. 3. Short press the SET button to select the working mode, and then enter the system parameter settings. 4. In the system parameter setting interface, short press the "SET" button to switch the system parameter to be modifified, and short/long press the UP / DOWN button to modify the value. Note: In modes P1, P2, P3, P7, short pressing'SET' is invalid. In the OP/CL parameter modifification interface (flflashing), short press the "STOP" button to enter the setting interface and select the timing range (1s/0.1s/ 0.01s / 1min). After setting all the parameters, long press the "SET" button to save the parameter settings and exit the setting interface. UART communication and parameter setting: The system supports UART data upload and parameter setting function (TTL level) QQ截图20201118143010

OFF Relay disabled 12. PX Setting mode P1~P7 Application Scenario: 1. Engine 2. Robot 3. Smart home 4. Industrial control 5. Automatic irrigation 6. Indoor ventilation Additional Features: 1. Automatic sleep function: Long press the "Stop" button in the normal operation interface to turn on or offff the automatic sleep function. L-p: ON, turn on the automatic sleep function. L-p: OFF, turn offff the automatic sleep function. 2. Relay function selection: Short press the "STOP" button in the normal operation interface to turn on or offff the relay delay function. 'ON': When the conduction condition is met, the relay usually opens. 'OFF': Even if the conduction conditions are met, the relay is usually closed. The LCD will flflash "OUT" in the OFF state.
