Connect any device... Monitor & control over the web
Our Ethernet I/O products are designed to be extremely reliable for web control and monitoring of electrical devices. We feature a variety of I/O products, such as the original WebRelay™ which is a web-controlled relay with a digital input that we developed back in 2005. Since then, we have been making top-of-the-line products for industrial automation, data collection, and monitoring.
Many of our products include various inputs and outputs such as relays, digital inputs, analog inputs, 1-Wire bus for monitoring temperature & humidity, etc. that can be used with our built-in software to remote control/monitor electrical devices. Most of our I/O products support email notifications, scheduling, logging, BASIC interpreter, communication with a variety of protocols (Modbus, SMNP, SMTP, etc.), and many more features.
All ControlByWeb™ products have built-in web servers and can be setup, monitored, and controlled using a web browser. In addition, our products can be monitored and controlled using custom computer applications as well as our CBW Mobile app for all smart phones and tablets.
Web-Enabled Drop-In Solutions for Remote Monitoring & Control
Remote Relay Control
ControlByWeb™ Ethernet I/O products provide an easy and reliable way to monitor and control electric devices over a network. Every product is designed for simplicity and rock-solid performance, making remote relay control straight-forward and dependable.
All of our products have built-in web servers, allowing them to be accessed by a standard web-browser. There is no special software or app required, no drivers to install, and no monthly subscription.
ControlByWeb Ethernet I/O products can be easily integrated into SCADA and industrial automation systems (using Modbus / TCP) or they can be used as single, stand-alone devices right out of the box. You can even use our products in pairs (peer-to-peer) to send I/O communications over IP networks without using an external controller.

How to use ControlByWeb products
ControlByWeb's Ethernet I/O products can be used as a stand-alone device that can be integrated with an existing system.
They can also be used in peer-to-peer mode where multiple ControlByWeb products can communicate with each other, allowing you to control outputs based on another devices output or input status.
ControlByWeb's stand-alone products can be used as slave modules to controllers such as the X-600M™ Web-Enabled Programmable Logic Controller.
