Feature:1. The delay relay module has 32 common functions, can meet more application needs2. Suitable for controling solenoid valves, water pumps, motors and light strips, etc.3. The time range is from 0.01 second to 999 minutes, any time can be adjusted4. Adopted of high quality electronic components, and accuracy process, ensure for the durability5. Professional design and reasonable structure, can control DC or AC load within 5ASpecification:Item Type: Delay Relay ModuleModel: YF-7Input Voltage: DC 7~30V optionalOutput Power: Can control DC or AC load within 5ATime Range: 0.01 second to 999 minutes, any time adjustableWiring Port Description: 1. +: Input power positive2. -: Input power negative3. IN+: Positive signal input terminal4. IN-: Negative signal input terminal5. NO: The relay normally open interface, the relay is suspended before the pull-in, and short-connected to the COM after the pull-in6. COM: Common interface of relay7. NC: Normally closed interface of the relay, the relay is short-connected with COM before it is closed, and it is suspended after it is closedList of Functions: You can set the functions arbitrarily after you buy them, and the manual is provided; any parameter set can be memorized when the power is offAll the functions in P-11 to P-44 are as follows; signal 1 corresponds to relay 1; signal 2 corresponds to relay 2; the two channels can be triggered at the same time; independent of each other; each other does not affect each other; each signal tube corresponds to each relayP-11: Jog (to pull in the signal relay, the signal disappears and the relay stops)P-12: Self-locking (turn on the signal relay once, and stop the signal relay again)P-13: Give the signal, and the relay will automatically stop after closing for A second; triggering is invalid during the delay periodP-14: Give the signal, the relay will stop automatically for A second; trigger to re-timing during the delay periodP-15: Give the signal, the relay will stop automatically for A second; during the delay period, the superposition timer will be triggeredP-16: Give the signal, and the relay will stop automatically for A second; trigger reset during the delay periodP-17: Give the signal, the relay is closed, the input signal is disconnected, and the power is turned off after the start of timing A second, and the signal is kept output during the delay period, and the timing stopsP-18: After the power is turned on, the relay will be turned on immediately, and the power will be turned off after a delay of A seconds; until the next power onP-21: Give the signal, after a delay of A second, the relay is closedP-22: Give the signal, after more than A second, the relay is closed, the signal disappears, and the relay stopsP-23: After the signal disappears for more than A second, the relay is closed, the signal disappears, and the relay stopsP-24: There is a signal. After A second, the relay is closed. After the signal disappears for more than A second, the relay stops.P-25: There is a signal. After A second, the relay is closed. When there is another signal for more than A second, the relay stops.P-26: When there is a signal, the relay will stop after closing for A second, and when the signal disappears, the relay will stop after closing again for A second.P-27: If there is a pulse signal, the relay stops; if there is no pulse signal, the relay will be closed for A second; (the signal continues or the signal disappears will be regarded as no pulse signal)P-28: After power-on, after a delay of A seconds, the relay will be closed until the power is offP-31: After power on, the relay is closed for A second, disconnected for B second, infinite loop; power off stopsP-32: When there is a signal, start P-31 infinite loop; when the signal disappears, terminate the loopP-33: Give a signal to start P-31 infinite loop; give another signal to terminate the loopP-34: After power-on, the relay will be closed after a delay of A seconds, and stop after being closed for B secondsP-35: There is a signal, after a delay of A second, the relay will be closed, and the relay will be closed after being closed for B seconds.P-36: When there is a signal, after A second, the relay will be closed, and after B second, the relay will stop, the signal disappears, and the timer will be cleared and stopped.P-37: If there is a signal, the relay will stop automatically for A second when the relay is closed, and then it will count for B seconds after it stops. The signal trigger is invalid within the time A+B.P-38: When there is a signal, the relay will automatically stop when it is closed for A second, and after stopping and counting for B seconds, it will stop automatically when it is closed again for A second.P-41: No action when there is a signal; trigger when the signal disappears; the relay is disconnected after a delay of A timeP-42: The signal disappears, after delaying time A, the relay works; working time B endsP-43: The signal disappears.
