Benefits of Cellular I/O Controllers
Simplify Installation
Our devices come out of the box with powerful features like our no-code browser-based UI, peer-to-peer device communications, and a configurable control page. These features simplify implementation and give technicians the confidence that their systems will work correctly.
Keep IT Happy
ControlByWeb cellular IoT controllers are ideal when existing networks are unavailable or where network requirements are stringent. IT managers are rightly concerned about security and the devices they allow. The approval process can be difficult. For many, skipping the local network by installing cellular devices makes a lot of business sense. Get your data faster and keep networks separate and secure.
Save Money On Fewer Devices
An embedded cellular gateway keeps costs low by limiting third-party devices needed to remotely monitor and/or control an asset or a process. Our controllers work great with other hardware, but why buy another device when you don’t need to? Save money and make your installation as easy as possible.
Ensure a Consistent Connection
Wired networks are generally considered to be the most reliable but that doesn’t mean it never fails. ControlByWeb cellular IoT devices have the ability to use cellular networking as the primary or as a failover network if ethernet goes out, ensuring that your data keeps flowing, regardless of your wired network conditions.
Why Cellular IoT?
Monitoring and control tasks vary widely from one application to the next. Cellular networking on IoT logic controllers adds the network flexibility you need to build solutions quickly and effectively.
Remote Monitoring Made Easy
There are a virtually unlimited number of ways to capture and use edge data. Some methods are (much) easier than others. We design controllers that are simple to set up thanks to the intuitive no-code Task Builder and browser-based UI. Our new cellular I/O modules go a step further with an embedded SIM for a true drop-in solution that’s ready to go in minutes.
That same capability using a non-cellular controller would require a wireless networking infrastructure like point-to-point 900 MHz radios, routes, cables and other hardwiring, etc. Then there’s the need for installation and setup of multiple third-party pieces of hardware. This is certainly viable but does increase cost and complexity.
Integrate your solutions faster and with less headaches by choosing ControlByWeb cellular IoT devices.

In this example, two X-412CW modules are being used to monitor tank level one two water tanks. One X-412CW is controlling a pump to manage the level between the two tanks. Both X-412CW modules communicate with each other over the cloud.
