Vszerda 2Pcs DC 5V Delay Relay Module Delay Relay Switch with Timer Adjustable Potentiometer 5V 0.1S Delay Circuit Board Disconnection Connection Function for Smart Home

The 5V delay relay module adopts relays with a maximum current of 10A. The module uses double-sided FR-4PCB board, and the overall layout of the module is reasonable, beautiful and generous. Using original high-performance delay chips for better performance. Equipped with a delay adjustment potentiometer, the shortest time is 0.1 seconds and the longest can reach 1 hour. It also has an anti reverse power protection diode, which can effectively protect the product.

Maximum frequency of switch: 5KHz

Product weight: approximately 22g

Structural dimensions: 57 * 30 * 18.5mm (length * width * height)

Positioning hole size: 52*25mm

Interface Description

1. When it comes to modules When the S6 jumper cap is plugged in and the S7 is not plugged in, the module immediately starts timing (with an adjustable time range) as soon as the power is turned on. At the same time, the relay is immediately closed, and the common terminal of the relay is connected to the normally open terminal. After the delay ends, the relay is released, and the common terminal is connected to the normally closed terminal.

2. When the S7 jumper cap is plugged in on the module and S6 is not plugged in, as soon as the module is powered on, it immediately starts timing (with an adjustable time range). At this time, the relay does not close (not connected), the delay ends, the relay closes, and the common terminal and normal start are connected.

Potentiometer adjustment time range

S1:0, S2:1, Without S4:0.13-1.3s; With S4:1.5-14.5s

S1:1, S2:0, Without S4:0.5-5.2s; With S4:6-58s

S1:0, S2:0, Without S4:4.4-42s; With S4:48-463s

S1:1, S2:1, Without S4:38-340s; With S4:389-3700s

Reminder: When the relay controls AC 220V or other DC power supply voltages greater than VCC, the jumper cap S5 cannot be inserted. If S5 is inserted in this way, high voltage will flow back into the module, which will burn out the module.
