Product Description
DC 12V Time Delay Relay Module Delay Turn On / Delay Turn Off Relay Switch Module With Timer DC 12 V Volt Timing Relays Board Product introduction: 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. Product parameters: Delay relay module power-on delay Supply voltage: 5V/12V Quiescent current: 2.5mA/5.5mA Maximum working current: 70mA/42mA Load voltage: DC 30V or AC 250V Load current: 10A Relay life: more than 100,000 times Maximum switching frequency: 5KHz Product weight: about 22g Structure size: 57*30*18.5mm (length * width * height) Positioning hole size: 52*25mm Interface Description: 1. When the S6 jumper cap on the module is plugged in and the S7 is not plugged in, the module will start timing as soon as the power is turned on (the time range is adjustable), and the relay will be closed immediately, and the common terminal of the relay will be connected to the normally open terminal. , The delay is over, the relay is released, and the common terminal is connected to the normally closed terminal. 2. When the S7 jumper cap on the module is plugged in and S6 is not plugged in, as soon as the module is powered on, it will start timing immediately (the time range is adjustable), at this time the relay is not closed (not connected), and the delay is over , The relay is closed, and the common terminal is connected to the normally open terminal. 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.![]() ![]() ![]() ![]() ![]()
