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 todotcom after it is closed.
COM: Relay common interface
NC: Normally closed interface of the relay, short-circuit withdotcom 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. After the time A exceeds, the relay works; the working time B ends
P-44: After giving the signal more than A times, the relay will be closed for B seconds and stop
P-45: After power-on, relay 1 will work for A second and then disconnect; Relay 2 will work for B second and disconnect
P-46: Give signal 1, after relay 1 works for A seconds and disconnects; relay 2 works for B seconds and disconnects
P-47: Give signal 1, after relay 1 works for A second; relay 2 starts to work; after B second, relays 1, 2 are disconnected at the same time
P-48: After power-on, relay 1 works for A seconds and disconnects; stops for B seconds; relay 2 works for C seconds and disconnects and stops for D seconds;

Note:
There may be slight size deviations due to manual measurement, different measuring methods and tools.
The picture may not reflect the actual color of the item because of different photographing light, angle and display monitor.
