Description
12V 30A Timing Delay Relay Module NE555 Timing On Off Switch Industrial Control High Current Delay Time Relay Module
Product Description
Name: Multifunctional Delay Relay Module A control module specially designed for delay function, used for function control of health, industrial control, toys and other products
Features
●Using dedicated time chip NE555 as the main control, the time is accurate and stable; ●This model can be set to one of the following two working modes: A turns on immediately after power on, and turns off after the delay arrives (keep off until the input is powered off); B will not act after power-on, and will be turned on after the delay is reached (keep on until the input is powered off). Through the jumper setting on the board, you can switch between functions A and B, and the default setting is A mode when shipped. ●Adopt an adjustable resistor to adjust the time, and the delay range is 0-5 seconds/1-45 seconds/1 second and 200 seconds to choose from; ●No need to start externally, it will automatically enter the delay state after power on; ●The typical design working voltage is 12V DC. ●Standby power saving, only 3mA current. ●Power supply protection against reverse connection. Connecting the positive and negative of the power supply will not work, nor will it burn out the module.
Function brief
Mode A: After the module is connected to the power supply, the red indicator light is on to indicate that the power is normal. The relay works immediately, the green indicator light is on, and the normally open and common terminals are switched to the connected state (the normally closed terminal is disconnected). After some time, the relay When the switch is disconnected and the green indicator light is off, the normally open and common terminals are switched to the disconnected state (the normally closed terminal is connected). Keep this state until the input is powered off. Mode B: After the module is connected to the power supply, the red indicator light is on to indicate that the power is normal. The relay will not operate and the green indicator light is off. At this time, the normally open and common terminals remain in the disconnected state before power-on (the normally closed terminal is connected). After a period of time, the relay is turned on and the green indicator light is on. At this time, the normally open and common terminals are switched to the connected state (the normally closed terminal is disconnected). Keep this state until the input is powered off.

Load capacity
|
30A, Resistive load, can withstand 30A 250V AC or 30V DC; For capacitive loads, current buffer devices must be added, such as inductors, NTC current limiters, etc.; For inductive loads, voltage absorption devices should be added, such as series resistors,
capacitors, and varistors. For motors, the starting current should be considered. |
