Built around simple relays
A digital signal is a signal that exists in one of two states: high or low, open or closed, on or off. A digital input/output (DIO) device is hardware that sends or receives these digital signals. DIO devices are usually built around simple relays such as reed relays. These relays are normally open but close when power is sent to them. When the relay closes, it sends a signal that communicates a message or triggers another device.

A digital signal is a signal that exists in certainly one of states: high or low, open or closed, on or off. A digital input/output (DIO) device is hardware that sends or gets those digital signal. DIO devices are generally built round simple relays which include reed relays. These relays are usually open however close while power is received. When the relay closes, it sends a signal that communicates a message or triggers any other tool.
DIO devices can be either input only, providing input from sensors; output only, sending signals to activate a device; or bidirectional, providing both input and output signals.
These are some of the applications that use DIO:
Alarm: An alarm can be sounded with Digital input sensors which can detect an abnormal condition such as heat or water.
Industrial controls: Industrial devices such as Programmable Logic Controllers (PLCs), mostly found in the manufacturing process provide a hardware interface for DIO signals.
Hobbyists: Hobbies such as robotics and railroading use DIO devices are due to its versatility and can often be controlled from home computers.
In the world of automation and control systems, you may have encountered the term “Modbus Gateway.” But what exactly does this term mean? How does it function, and why is it vital in our technology-driven world? This article is your comprehensive guide to understanding Modbus Gateway.
Modbus, an established communication protocol used extensively in industrial control systems, has withstood the test of time due to its simplicity and ease of deployment. But, as with any technical protocol, understanding error codes is essential to ensure smooth operation.
Modbus communication is not a new term in the industrial automation field. Established in 1979 by Modicon, it has become a de facto standard communication protocol, especially in the realm of industrial automation. How has it managed to stay relevant over all these decades, you ask? Well, its simplicity, reliability, and open-source nature have played significant roles in its longevity.
Discover the many ways a Modbus RTU Converter can benefit your industrial automation systems.
Modbus is a communication protocol developed by Modicon systems. Primarily used with Industrial devices, it’s designed to allow these devices to communicate over various types of media, including both wired and wireless networks.
Before diving into the world of Modbus to Ethernet converters, it’s essential to understand these two key concepts individually.
