The X-320™ is a high-end web-based instrumentation module that can be used in a variety of scientific and industrial applications such as energy/power monitoring, meteorology, process control, and much more.

It has a combination of analog and digital inputs that can be used with the appropriate sensors* for measuring voltage, current, temperature, wind speed, solar radiation, fluid level, flow, frequency, count, etc. Two digital inputs can be user-configured as outputs capable of driving solid state relays or triggering the input of another controller.

Like all of the ControlByWeb products, the X-320 has a built-in web server and all of the data it measures can be viewed using a web browser (or custom computer application). Setup is simple; There is no app to download, no subscription to buy, no software required, and no programming required for setup or use. Even with its simplicity, the X-320 has many advanced features including the ability to create BASIC scripts, SNMP, peer-to-peer communications, email alerts, and full calendar scheduling.

The X-320 is designed for accuracy and reliability, and is an innovative solution for a number of applications.

* Sensors can be purchased from a variety of sources. X-320 does not include sensors.


The X-320 is versatile and has many applications. A few examples are listed below.

The X-320’s powerful and flexible design make imagination its only limit.
