High-power relay module RFID control self-locking delay power-off on off one-button start-stop switch board

Description of function list:

P--1: Self-locking, give a signal relay to pull in (work), and then give a signal relay to stop (stop)

P--2: There is a signal, the relay pulls in, the input signal is disconnected, and the output power is cut off after a period of time; during the delay period, the signal is given again to keep the output, and the timing stops, which is equivalent to a power-off delay

P--3: Give the signal, the output will automatically stop for a period of time; the signal will be invalid during the delay period;

If the signal is directly short-circuited, it can be realized: the power-on output will be disconnected for a period of time until the power is turned off

P--4: When the signal exceeds a certain time, the output works; when the signal disappears, the timer is reset and the output stops

If the signal is directly short-circuited, it can be realized: the relay automatically picks up after a period of time when the power is turned on until the power is turned off

Module interface description:

1. DC+: positive pole of external DC power supply

2. DC-: Negative pole of external DC power supply

3. IN: Signal input terminal (positive trigger, high level, can be connected to buttons, PNP sensors, etc.)

4. NO: The relay is normally open interface, the relay is suspended before the pull-in, and shorted with COM after the pull-in

5. COM: Relay public interface

6. NC: The normally closed interface of the relay, the relay is shorted with COM before the pull-in, and it is suspended after the pull-in
