AZDelivery 2 Channel Relay Module DC 5V with Optocoupler Low Level Trigger Shield Board Compatible Arduino and Raspberry Pi Including E Book!

✅ This microcontroller compatible board with two relays for max. 50V AC / 5A or 30V DC / 5A each is perfect for all different DIY projects and 100% compatible with many applications. ✅ This 5V 2-channel relay module with optocouplers is perfect for controlling up to 2 devices with higher current. ✅ The optocouplers are used to transmit the signals between the two galvanically isolated circuits - e.g. your connected device with higher current. ✅ There is also an LED indicator attached to the module to show the relay output status. Each channel of the module is additionally connected to an LED, which indicates the switching status of the relay. Due to the practical drill holes, the module can be safely installed. ✅ This product includes an E-Book that provides useful information on how to begin your project, it helps with a quick setup and saves time on the configuration process. We provide an array of application examples, full installation guides and libraries.
