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.

New five-year warranty for all ControlByWeb products.
