: Each channel provides Normally Open (NO) , Common (COM) , and Normally Closed (NC) contacts. Specifications
Most 5V relay modules are Active-Low , meaning the relay activates when the input signal is 0V (GND) and deactivates at 5V (VCC).
In the world of electronics and automation, relay modules play a crucial role in controlling and switching high-power devices. A 4-channel relay module is a popular choice among electronics enthusiasts and professionals alike, as it allows for the control of multiple devices simultaneously. When it comes to simulating and testing relay modules, Proteus is a widely used software that offers a comprehensive environment for circuit design and simulation. In this article, we will explore the 4-channel relay module library for Proteus, its features, and how to use it effectively.
