Features
– Using the dedicated time chip NE555 as the main control, the time is accurate and stable;
– This section can be set to one of the following two modes of operation
A—power on immediately, disconnect after the delay arrives, (maintained disconnected until the input is powered off);
B—The power is not activated first, and the delay is reached after the delay is reached (always on until the input is powered off).
The jumper settings on the board allow you to switch between functions A and B. The default is set to A mode.
– Adjust the time with an adjustable resistor. The delay range is 0-5 seconds / 1-45 seconds / 1 second – 200 seconds.
– No external start required, power will automatically enter the delay state;
– Typical design operating voltage is 12V DC.
– Standby power saving, only 3mA current.
– Power protection against reverse protection. The reverse power supply will not work and will not burn the module.
Mode Description
A mode:After the module is connected to the power supply, the red indicator light indicates that the power is on. The relay works immediately and the green indicator light is on. At this time, the normally open and common terminals are switched to the on state (the normally closed terminal is disconnected). After a period of time, the relay is turned off and the green indicator light is off. At this time, the normally open and the common terminal are switched to the off state (the normally closed terminal is turned on). Keep this state until the input is powered off.
B mode:After the module is connected to the power supply, the red indicator light indicates that the power is on. The relay does not move, the green indicator light does not illuminate, and the normally open and the common terminal remain in the off state before the power is turned on (the normally closed terminal is turned on). After a period of time, the relay is turned on and the green indicator light is on. At this time, the normally open and the common terminal are switched to the on state (the normally closed terminal is disconnected). Keep this state until the input is powered off.
