5V Dual-Channel Relay Module

The dual-channel relay module is more or less the same as a single-channel relay module, but with some extra features like optical isolation. The dual-channel relay module can be used to switch mains powered loads from the pins of a microcontroller.

5V Single-Channel Relay Module

Relay is an electromechanical device that uses an electric current to open or close the contacts of a switch. The single-channel relay module is much more than just a plain relay, it comprises of components that make switching

Relays and Contactors: Types, Working and Difference between them

Relays are basically switches which are primarily used for the protection of equipment. It generally uses two circuits – A control circuit and a power circuit.
