12V Power On Time Delay Relay Module, Adjustable Delay Timer Circuit Board, for Automation Projects

Product description Description The 5V/12V delay relay module uses high-quality relays with a maximum current of 10A. The module uses double-sided FR-4 PCB boards. The overall module layout is reasonable and beautiful. Use original high-performance delay chip, better performance. With a delay adjustment potentiometer, the shortest is 0.1S, the longest can be up to 1 hour, and it has a protection diode against power reverse connection, which can effectively protect the product. The module can be used in various control situations such as driving recorder, GPS start protection, household appliances, electronic equipment protection, PLC control, industrial control, electronic experiment, for arduino robot, etc.

Note: When the relay controls AC 220V or other DC power supply voltage greater than the VCC terminal, the jumper cap S5 cannot be inserted. If S5 is inserted in this case, the high voltage will flow back into the module, which will burn the module.
Instructions for use: When the relay is in pull-in, the common terminal is connected to the normally open terminal, and both ends of the load have electricity to work. When the relay is off, the common terminal is connected to the normally closed terminal, and the load does not work without electricity. Load current capacity of 10A Maximum current of 10A for versatile applications High-performance delay chip for better performance FR-4 PCB boards Protection diode against power reverse connection Suitable for driving recorders and GPS...
