Relay module delay power off and trigger delay cycle timing circuit switch Timing Range:0.01 sec~9999 min This product lcd display, very clear, simple and easy to use, powerful, but please read user instructions carefully before using. Product Highlights: Display with LCD two columns, Can display parameters directly; Trigger mode: high and low level,switch quantity.meet most of the needs. Power supply: 6~30V, also supports micro USB 5.0V, very convenient.Anti back connection of power supply. Parameters can be modified via UART. Stop button to provide emergency stop function. 5 minutes without any operation into a low-power state. Any action wake up. OP/CL/LOP params can be modified individually All parameters are automatically saved by power off. Working mode: P1: after the signal is triggered, the relay turns on the op time, and then turns off; within the op time, the signal triggers again and is invalid ; P2: after the signal is triggered, the relay turns on the op time, and then turns off; within the op time, the signal triggers again and counts again ; P3: after the signal is triggered, the relay turns on the op time and then turns off; within the op time, the signal triggers the reset again, the relay turns off and stops timing P4: give the trigger signal. After the relay disconnects CL time, the relay turns on OP time. After the timing is completed, disconnect the relay; P5: give the trigger signal, after the relay turns on OP time, the relay turns off CL time, then cycle the above actions, give the signal again in the cycle, the relay turns off and stops timing; the number of cycles (LOP) can be set; P6: after power on, no trigger signal is required, the relay turns on the op time, the relay turns off the CL time, and circulates the above actions; the number of cycles (LOP) can be set; P7: if the signal holding function has trigger signal, the timing will be cleared and the relay will remain on; when the signal disappears, the relay will be disconnected after timing OP; during the timing, there will be another signal, and the timing will be cleared; Product Parameters: Power Supply: 6V~30V and micro USB 5.0 V Trigger signal source: High level(3.0V~24.0V),Low level(0.0V ~0.2V),Switch signal. Maxmum Output load: DC 30V 5A and AC 220V 5A. Static Current: 15mA Operating current: 50mA. Service life: more than 100,000 times; working temperature: -40-85°C; size: 8.0*3.8*1.9cm. Optocoupler isolation,Strong anti-interference ability, Industrial grade circuit board Timing Range: 0.01 sec~9999 min How to choose the timing range: In the OP/CL parameter modification interface, press the STOP button shortly to select the timing range. XXXX Timing range:1sec~9999sec XXX.X Timing range:0.1sec~999.9sec XX.XX Timing range:0.01sec~99.99sec X.X.X.X Timing range:1min~999.9min For example, if you want to set the OP to 3.2 seconds, move the decimal point to ten digits. LCD display 003.2 Parameter Description: OP on-time, CL off time, LOP cycle times (1 - 9999 times, "----" represents an infinite number of cycles) Parameter setting a) Press and hold the set key to enter the setting interface; b) First, set the working mode, the working mode flashes to remind, and set the working mode by short pressing the up / down key; c) Press the set key briefly to select the working mode and enter the system parameter setting; d) In the system parameter setting interface, short press the set key to switch the system parameter to be modified, short press / long press the up / down key to modify; (Note: in the P-1 ~ P-3 and p-7 modes, short press set is invalid); e) In the op / CL parameter modification interface, short press stop to switch the timing unit (1s / 0.1s/0.01s/1min); f) After all parameters are set, long press the set key to save the parameter settings and exit the setting interface; Remote data upload and parameter setting functions: The system supports UART parameter reading and writing functions; UART:9600,8,1
