Smart Relays with Simple No-Code Logic
Remote Relays | Ethernet / Network Relays | Wi-Fi Relays | Cellular Relays | Peer-to-Peer Communication
Ethernet-capable smart relays designed to be extremely reliable for monitoring and control of industrial equipment. We feature a variety of I/O products, such as the original WebRelay™, a networked relay with one digital input and one relay originally developed in 2005. Since then we’ve been making top-of-the-line products for industrial automation, data collection, and device monitoring.
Many of our products include various inputs and outputs such as relays, digital inputs, analog inputs, 1-Wire bus for monitoring temperature and humidity, etc. that can be used with our built-in software to remote control/monitor electrical devices. Our latest (400 Series) I/O products support email notifications, scheduling, logging, BASIC interpreter, communication with a variety of protocols—including MQTT, Modbus, SMNP—and many more features. Each features a truly Open API, ready to integrate with any industrial system.
Browser-Based User Interface
Our products have a built-in web server that allows I/O to be monitored or controlled with a standard web browser. No additional software is needed.
Simple No-Code Programmable Logic
Each of our latest IoT controllers (400 Series) feature an easy-to-use user interface with drop down menus to build conditional and scheduled events. The menu system lets you build impressively powerful if/then logical events. These smart relays are capable of many monitoring and control tasks in industrial settings.
Integration Ready
Our smart relays are ready to integrate with your system. They feature an open API (HTTP) as well as popular, open industrial protocols such as MQTT (regular and Sparkplug B) and Modbus TCP/IP. You won’t find any walled gardens here.
ControlByWeb Cloud Compatible
We’ve made remote access and control even easier with the ControlByWeb Cloud. Enjoy easier access, cloud-based logging, dashboards, reports, and optional parent/child accounts. For more information, visit our cloud page.
Note: Our IoT controllers do not require connection to our cloud service, which is important to us. There are no forced subscriptions to worry about. The controllers will work with any cloud system through our open API, or through our very own cloud API.
