One relay module 12V disconnects and triggers the delay power off cycle timing circuit switch

Description of wiring port:
1. DC+ : positive pole of input DC power supply
2. DC- : negative pole of input DC power supply
3, IN+ : signal input pole
4. IN- : negative terminal of signal input
5, NO: relay normally open interface, the relay is suspended before the suction, after the suction and COM short
6, COM: relay public interface
7. NC: normally closed interface of the relay. The relay is short connected with COM before it is absorbed and suspended after it is absorbed
6: function list:
P-11: inching (imbibing signal relay, signal vanishing relay stops)
P-12: self-locking (suction the signal relay once and stop the signal relay once again)
P-13: to signal, relay suction A second automatic stop; The trigger is not valid during the delay
P-14: to signal, relay suction A second automatic stop; The reset is triggered during the delay
P-15: to signal, relay suction A second automatic stop; Triggers the stack timer during the delay
P-16: to signal, relay suction A second automatic stop; The reset is triggered during the delay
P-17: for the signal, the relay is sucked in, the input signal is disconnected, and the power is off after A second of timing. During the delay, the signal is kept in the output again, and the timing stops
P-18: after the power on, the relay will snap on immediately and the power will be cut off after the delay of A second; Until the next power on
P-21: for the signal, delay A second, the relay suction
P-22: for the signal, more than A second after the relay suction, signal disappeared, relay stop
P-23: when the signal disappears for more than A second, the relay will close, the signal disappears and the relay stops
P-24: when the signal exceeds A second, the relay will close, and when the signal disappears for more than A second, the relay will stop
P-25: after the signal exceeds A second, the relay will close, and after the signal exceeds A second again, the relay will stop
P-26: stop after the signal relay absorbs for A second, and stop after the signal disappears after the relay absorbs again for A second
P-27: pulse signal is detected and the relay stops; No pulse signal, relay delay A second suction; (signal duration or signal disappearance are considered to be without pulse signal)
P-28: after power on, after A second delay, the relay is sucked in until the power is cut off
P-31: after energizing, the relay absorbs for A second, disconnects for B second and circulates indefinitely; Power to stop
P-32: there is a signal to start p-31 infinite loop; The signal disappears, terminating the loop
P-33: give a signal to start p-31 infinite loop; Give the signal one more time to terminate the loop
P-34: after energizing, delay for A second, the relay will close and stop after B second
P-35: there is A signal. After delay of A second, the relay will close and stop after B second
P-36: there is A signal. After more than A second, the relay will close and stop after B second. The signal will disappear and the timing will be reset and stop
P-37: when there is A signal, the relay will stop automatically after A second of absorption, and then start B seconds after the stop. The signal trigger is invalid within A+B time
P-38: when there is A signal, the relay will stop automatically after A second of suction, and the relay will stop again after B seconds of timing
7: key setting instructions: "--" on power indicates standby state;
Press K1 for the first time (it needs more than 1 second to be effective to prevent false triggering), and display: p-11: K2 adjust the main mode, K3K4 adjust the function
Press the second K1, the screen will show: a001:k2 and K3 to adjust the first time A, and K4 to adjust the decimal point (time unit).
Press K1 for the third time, the screen will show: b001:k2 and K3 to adjust the second time, B, and K4 to adjust the decimal point (time unit).
Press K1 for the fourth time, and "--" indicates standby state
Press K4 in standby mode to permanently close/open the display and switch to low-power mode
8: description of decimal time unit:
X.XX decimal point in the hundreds, timing range: 0.01 seconds to 9.99 seconds
X decimal point in the tens place, timing range: 0.1 seconds ~99.9 seconds
XXX has no decimal point, timing range: 1 second ~999 seconds
XXX. Decimal point in the ones place, timing range: 1 minute to 999 minutes
