Product Function: The KF301 relay module is used to control AC circuits, switching them on or off. It's an electrical switch that responds to a signal received from a microcontroller (like in Arduino or Raspberry Pi). Output Drive Capacity: 10A 250V AC, 10A 125V AC, 10A 30V DC, 10A 28V DC. Operating Voltage: 5V/12V. Design Advantage: Diodes drive to increase relay coil. The relay can be used not only as a module for single-chip development boards but also as a household controller. Wide Application: It's widely used in IoT projects to control lights and other electronic devices, such as remote controls, communication, mechatronic devices, powerful electronic devices, etc. Type: 1 Channel Operating Voltage: 5V/12V Output Drive Capacity: 10A 250V AC 10A 125V AC 10A 30V DC 10A 28V DC Package Includes: 5 × 5V 1 Channel Relay Module
