What is a Relay Module? – RY-ELE I/O 4-in-1 Relay Module for Industrial Automation
Introduction
In modern automation and control systems, relay module are essential components that help engineers switch, control, and protect circuits. But what exactly is a relay module, and why is it widely used in industrial automation, panel building, and smart systems?
This article explains the basics of a relay module, followed by an introduction to the RY-ELE I/O 4-in-1 relay module, a compact and reliable solution for control cabinets and automation projects.
What is a Relay Module?
A relay module is an electrical device that integrates relays with I/O interfaces, making it easier to connect control signals to power loads. Unlike a single relay, a relay module for industrial automation offers better installation convenience, higher efficiency, and simplified wiring for control cabinets.
The RY-ELE I/O 4-in-1 relay module is designed for engineers and panel builders who need reliable switching in compact spaces.
