A relay module, available in configurations such as 4-channel (4CH) serves as a crucial component in various electronic circuits, allowing for the control of high voltage/current devices using low power signals. Operating at 5V, these modules facilitate the interfacing between microcontroller outputs and electrical loads that can be significantly higher in power than the controlling signals. Each channel corresponds to a relay capable of independently switching a separate circuit. The modules typically come with LED indicators for each channel, showcasing the relay's operational status, and offer both normally open (NO) and normally closed (NC) connections to accommodate diverse applications.
