ITEM NAME:DC 12V LED Digital Time Delay Relay Module Programmable Cycle Relay Switch Product Description Description: DC 12V LEDÂ Digital Time Delay Relay Module Programmable Timer Relay Control Switch Timing Circuit Trigger Cycle Adjustable Switch Relay Module Features: 1. Output optocoupler isolation to enhance anti-interference ability power consumption. 2. Industrial grade circuit board, set the parameters for permanent memory after power off. 3. The relay output is a passive contact, with no power output, controlling the function of a line. 4. Can control devices within 30V 5A or within 220V 5A. Operating mode: P-1: The signal triggers the relay to pull in and closes. During the delay period A: Invalid again, C: Trigger re-clocking again, E: Trigger relay reset termination timing again. P-2: Signal trigger start timing time T1, time is up to relay pull-in time T2 disconnect (reset). A: Invalid again, C: Trigger re-clocking again, E: Start delay without triggering power on. P-3: Cycling: Turn on T1, disconnect T2, infinite loop. The time of T1 and T2 is adjustable. If a parameter is turned on or off to 0, the power-on delay can be turned on or the power-on time-delay power-off does not cycle. A: The relay is turned on immediately after power-on, C: The relay is turned off and then turned on after power-on. P-4: There is signal, the relay is closed, the suction is kept, the signal disappears, the timing starts, the time is up, the relay is disconnected. During the delay, the signal is given again, the delay is cancelled, the relay is held, the signal disappears, and the timer is re-timed. P-5: Trigger once when the time X is reached. When the time is reached again, the output is for.P-3: Cycling: Turn on T1, disconnect T2, infinite loop. K2: Shift key: Press to adjust the flashing position of the digital tube, K3 adjusts the value of the digital tube flashing digital tube. K3: When the digital tube is flashing: K3 adjusts the digital change, and 0 to 9 change sequentially.
