Truly Open, No-Code Edge Controllers
ControlByWeb Industrial IoT controllers offer the flexibility you need to create the perfect solution for data acquisition and control. They can be used locally or remotely within a larger system or as standalone devices. Our Open REST API and open industrial protocols allows you to use common languages like HTTP, MQTT, and MODBUS to integrate our devices with virtually any third-party system.

Three Easy Ways to Access Your Data

Open REST API
Our REST API uses simple, well understood, and battle-tested HTTP Get requests to poll data, access log files, and control relay states from custom software, or from popular industrial platforms such as Ignition, TIA Portal, and more. This is quickly becoming the integration method of choice for many software engineers.

Open Industrial Protocols
We prioritize compatibility and ease of use by incorporating MQTT, Modbus TCP/IP, and SNMP into our edge controllers. This makes integration with virtually any industrial control system, SCADA, or IoT platform easy. These open protocols are industrial standards and have broad compatibility.

ControlByWeb Cloud API
Our optional cloud service makes remote access to data much easier with a simple UI and an open API. Build apps and interfaces that pull data from our devices via our cloud. Poll devices and send relay commands for full I/O access from anywhere.

Integration Spotlight: Industrial Ventilation Inc.
This ControlByWeb case study highlights IVI system designer Thad Failor, who built an all-in-one control panel that uses ControlByWeb modules communicating with their software via our Rest API, using HTTP GET requests. Our hardware allows the control system to monitor and control large scale HVAC equipment. Thad said that “the whole system together gives the storage manager the tools they need to be able to successfully store the product at the optimal conditions.”
Our edge controllers play a key role in agricultural temperature and humidity control. In this case, they’re connected to finely tuned equipment to monitor and control temperature, humidity, airflow, and CO2. They’re doing what they do best—monitoring sensor data, sending it back to the control software. The software processes the data and sends command back to ControlByWeb I/O modules that, in turn, control fans, lighting, HVAC units, humidifiers, and motorized doors and vents.
Cellular + Cloud
Our cell-enabled edge controllers increase installation flexibility dramatically, giving more options for integrated systems no matter where they’re located or how dispersed they may be. Each cell device also comes with WiFi and Ethernet, so they can failover to either one-adding an uncommon layer of reliability to remote applications.
The ControlByWeb Cloud provides remote access to each of our cellular devices at no additional cost (included in the data plan). Enjoy dashboards, reports, data logging, and more.
Knowledgeable In-House Technical Support
A lot of effort has been put into designing and manufacturing I/O modules that are easy to use and reliable. We put in the same amount of effort to support customers and integrators. That’s why when you call our support number, you’ll quickly be connected to one of our in‐house technical support technicians here in Nibley, Utah.

Backed by Our 5-Year Warranty
Our I/O modules are used across industries and in many unique applications; they’re equipped to handle almost anything. They’re designed, manufactured, and supported in the U.S. using only high‐quality components. We stand behind our controllers with an industry‐best 5‐year warranty.

No‐Cost Demo Units
We offer free demo units to select integrators and OEMs so you can familiarize yourself with our relays and ensure they’ll work for you. Discuss your options with our sales engineers.
Priority Support
Our support team works alongside engineering and sales at our headquarters in the USA. Integrators enjoy priority phone and email support. When you reach out, we’ll be there with the answers you need.
Same‐Day Shipping and Short Lead Times
Most ControlByWeb inventory is in stock and ships on the same business day. We avoid just‐in‐time manufacturing and keep a 6‐12 month store of raw components on hand to protect from any supply chain challenges.
White‐Label Cloud
Our hardware and cloud service can be tailored to your business with options for private or white labelling. The ControlByWeb Cloud can use your logo and colors and can also nest child accounts for resale access to customers.
Available Customizations
Product customization is available for integrators to streamline integration and protect your business. Here are some of the options:
- Custom Firmware
- Proprietary Part Numbers
- White Label
Access to our Supplier Network
We carry stock from partner suppliers, including brands like VEGA, George Risk Industries, and Phoenix Contact. We can directly source (and often stock) power supplies, contact switches, leak detector sensors, temperature sensors, liquids and solids level sensors, pressure sensors and switches, ethernet surge protectors, and more.
System Engineering Consultation
Our sales engineers can work with you in developing a new or updated system design. We stand behind years of I/O monitoring and control expertise and want to help integrators provide the best solution to their customers.
Schedule a 30‐minute call so we can better understand your application and determine if we’re a good fit.
