30A DC 12V Derailment Timing Module Timer Board 0.1 to 5 seconds

Features:1.Using the dedicated NE555 time chip as the main controller, the time is accurate and stable.
2.The jumper settings on the board allow you to switch between functions A and B.The default setting is one mode.
3.Adjust the time with an adjustable resistor with a delay range of 0.1 to 5 seconds.
4.No external start-up is required, and the power will automatically enter the delay state.
5.The typical design operating voltage is 12V DC.
6.Standby current is only 3mA, saving energy.
7.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 is off. At this time, the normally open and the common terminal are switched off (the normally closed terminal is turned on). Keep this state until the input is powered off.
Mode B: When the module is connected to the power supply, the red light indicates that the power is on. The relay does not move, the green light does not light up, and the normally open terminal and common terminal remain in the off-power state before power on (the normally closed terminal is activated). After a period of time, the relay is turned on and the green light is on. At present, the normally open terminal and the common terminal are switched to the ON state (the normally closed terminal is disconnected). Keep this state until the input is turned off.
