Professional design and reasonable structure, can control DC or AC load within 5A Specification: Item Type: Delay Relay Module Model: YF-7 Input Voltage: DC 7~30V optional Output Power: Can control DC or AC load within 5A Time Range: 0.01 second to 999 minutes, any time adjustable Wiring Port Description: 1. +: Input power positive 2. -: Input power negative 3. IN+: Positive signal input terminal 4. IN-: Negative signal input terminal 5. NO: The relay normally open interface, the relay is suspended before the pull-in, and short-connected to the COM after the pull-in 6. COM: Common interface of relay 7. 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 closed List 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 off All 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 relay P-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 period P-14: Give the signal, the relay will stop automatically for A second; trigger to re-timing during the delay period P-15: Give the signal, the relay will stop automatically for A second; during the delay period, the superposition timer will be triggered P-16: Give the signal, and the relay will stop automatically for A second; trigger reset during the delay period P-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 stops P-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 on P-21: Give the signal, after a delay of A second, the relay is closed P-22: Give the signal, after more than A second, the relay is closed, the signal disappears, and the relay stops P-23: After the signal disappears for more than A second, the relay is closed, the signal disappears, and the relay stops P-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 off P-31: After power on, the relay is closed for A second, disconnected for B second, infinite loop; power off stops P-32: When there is a signal, start P-31 infinite loop; when the signal disappears, terminate the loop P-33: Give a signal to start P-31 infinite loop; give another signal to terminate the loop P-34: After power-on, the relay will be closed after a delay of A seconds, and stop after being closed for B seconds P-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, i
