1. 【This microcontroller compatible board with 1 relay】 ： Output driver capacity: 250VAC-10A, 125VAC-10A, 30VDC-10A, 28VDC-10A; The 1-channel relay module is equipped with transistor and diode to switch higher loads safely, reliably and with little power. Thanks to its compact size, the 1-channel relay can be used in almost any project.
2. 【The module】 ： is also equipped with a generously dimensioned relay in order to be able to reliably carry out many switching processes. The module can be safely installed in housings thanks to the practical drill holes.
3. 【The channel of the module is also】 ： connected to an LED that indicates the switching status of the relay. The KY-019 relay is used to control AC circuits. The relay acts as a switch that responds to a signal. Because of this, it is widely used in IoT projects to control lights and other electronic devices.
4. 【Relays are suitable for driving high power electronic devices such as lights, electric fans and air conditioners】 ： This relay module can be used to control high voltage with low voltage by connecting it to an MCU
5. 【Controls DC or AC signals】 ： 220V AC load Working voltage: 5V; With operating display and signal output display
