Signal 1: Positive signal input terminalLeft 4. Signal 2: Positive signal input terminalLeft 5. Common Wire: Negative pole of signal input terminal (signal 1 and signal 2 share a negative pole)Right 1, Normally Closed 1: Relay 1 normally closed interface, the relay is suspended before being closed, and shorted to COM after being closedRight 2, Public 1: Relay 1 public interfaceRight 3. Normally Open 1: Relay 1 normally open interface, shorted to COM before the relay is closed, and suspended after being closedRight 4. Normally Closed 2: Relay 2 normally closed interface, the relay is suspended before the pull in, and short circuited with COM after it is pulled inRight 5. Common 2: Relay 2 common interfaceRight 6. Normally Open 2: Relay 2 normally open interface, the relay is short connected with COM before the pull in, and it hangs after pull inFunction List: You can set the function arbitrarily after you buy it, 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; do not affect each other; the respective relays of the respective signal tubesP-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 closed immediately, and the power will be turned off after a delay of A seconds; until the next time the power is turned 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
