Understanding the Dual Relay Module: A Key Component for Automation Projects
The Dual Relay Module is a fundamental component in many automation projects. It provides a simple yet effective way to control high-voltage or high-current devices using low-voltage control signals. This makes it especially useful in a wide range of applications, from home automation to industrial control systems. In this article, we’ll explore the essential features, applications, and considerations of using a dual relay module in various electronic projects.
What is a Dual Relay Module?
A Dual Relay Module consists of two separate relays integrated into a single circuit board. Each relay has its own input control, typically a low-voltage signal such as 3.3V or 5V, which activates the relay to control a high-voltage circuit. The module is designed to control devices operating on AC or DC power, often ranging from 5V to 250V, with current ratings typically around 10A for each relay.
