Jan 11, 2021 · 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.

A 4 channel relay module is an electronic device that allows you to control multiple electrical circuits using a microcontroller or other digital input signal. It consists of four separate relays that can be independently controlled to switch on or off different circuits.

Sep 19, 2024 · In a 4-pin relay, only the COM and NO contacts are used. Trace the Circuit Path: Follow the wiring diagram to see how the relay integrates into the circuit. Start from the power source and trace the path through the relay coil to understand how the …

By following a complete diagram guide, you can easily wire a 4-wire relay in your electrical system. First, it is important to identify the control terminal, which receives a low-voltage signal to activate the relay. This terminal is usually labeled with an “C” or “Coil” symbol.

This is a 5V 4-channel relay interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliances and equipment with large current. It is equiped with high-current relays that work under AC250V 10A or DC30V 10A.
