1XLeone Power Relay 12V-30A
The four–channel relay module contains four 5V relays and the associated switching and isolating components, which makes interfacing with a microcontroller or sensor easy with minimum components and connections. … They amplify the input signal so that they can drive the coils to activate the relays
