【High-Performance Isolation】 This 5V relay module features advanced patch photocoupler isolation, ensuring strong driving capability, superior anti-interference performance, and reliable stability. It can handle a maximum load of AC 250V/10A or DC 30V/10A on the normally open interface 【Usage Guidelines】Ensure the module is powered by a DC supply that matches the relay's voltage. The relay's common, normally open, and normally closed terminals function as a single-pole double-throw switch 【Interface Overview】VCC: connect to the positive pole of the 5V power supply (power supply according to the relay voltage), GND: connect to the negative pole of the 5V power supply, IN: the signal trigger terminal of the relay module (low-level trigger is valid) 【Versatile Applications】Designed to meet international safety standards, this module incorporates an isolation slot between the control and load areas, making it suitable for use with microcontroller development boards or home appliance automation 【Package Contents】 Your order includes five 5V single-channel relay modules and one 15-pin female-to-male Dupont cable, providing a comprehensive set for your project needs
