AZDelivery 5 x 1 Relay 5V KY 019 Module High Level Trigger compatible with Arduino including E Book!

5 x AZDelivery 1 Relay 5V KY-019 Module This microcontroller compatible board with 1 relay for max. 50V AC / 5A or 30V DC / 5A. 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. The module is also equipped with a generously sized relay to reliably perform many switching operations. Thanks to the practical holes, the module can be safely mounted in housings. The channel of the module is additionally 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. For this reason, it is widely used in IoT projects to control lights and other electronic devices. This product contains an e-book that contains useful information about the beginning of your project, it helps with a quick setup and saves time in the configuration process. We offer a range of application examples, complete installation guides and libraries.
