_x000D_ _x000D_ YF-7 Multifunctional Dual Channel Delay Relay Module Board Pulse Trigger Cycle Timer 0.01s-999m Delay Time Adjustable 7-30V DC Specification: Product model: YF-7 Input voltage: DC 7~30V Output power: can control DC or AC load within 5A Time range: 0.01 second to 999 minutes, any time adjustable Application: 32 commonly used functions to meet more application needs; it can control solenoid valves, water pumps, motors, light strips, etc. to run freely Wiring port description: +: Input power positive -: Input power negative IN+: Positive signal input terminal IN-: negative signal input terminal NO: The relay normally open interface, the relay is suspended before it is closed, and it is shorted to COM after it is closed. COM: Relay common interface NC: Normally closed interface of the relay, short-circuit with COM before the relay is closed, and hang in the air after being closed function list: The function can be set arbitrarily, and the manual is provided; Any parameters that can be memorized after power off are as follows: all functions in P-11 to P-44; 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; they do 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: When there is a signal, and the relay will automatically stop after closing for A second; triggering is invalid during the delay period P-14: When there is a signal, the relay will stop automatically for A second; trigger to re-timing during the delay period P-15: When there is a signal, the relay will stop automatically for A second; during the delay period, the superposition timer will be triggered P-16: When there is a signal, and the relay will stop automatically for A second; trigger reset during the delay period P-17: When there is a 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 closed immediately, and the power will be turned off after a delay of A seconds; until the next power on P-21: When there is a signal, after a delay of A second, the relay is closed P-22: When there is a 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: When 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: When 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: When 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 time P-42: The signal disappears, after delaying time A, the relay works; working time B ends P-43: The signal disappears.
