The XW-110 Plus is easy to use and can quickly be mounted to a wall or other workable surface. It can run on battery power and can be configured to send out a notification in the event of a power loss. As a self-contained device, no additional servers or software are required to provide live, real-time temperature status through a standard web browser.

XW-110 Plus Features

  • Temperature Logging
  • Email Notifications
  • AC Power Failure Notification*
  • Temperature probe Range: -67°F to 257°F (-55°C to +125°C)
  • Temperature Probe Accuracy: ±0.5°C (from -10°C to +85°C)

*This feature requires AA batteries to be installed and backup power must also be provided to the local network that provides internet connectivity.

Wireless Temperature Sensor Applications

As a standalone device, the XW-110 Plus excels in a wide variety of applications where it can be used as a drop-in solution where hard wiring isn’t practical or convenient. Some examples include:

  • Refrigeration/Freezer systems
  • Commercial properties
  • Water treatment plants
  • Chemical plants
  • Pharmacies
  • Laboratories
  • Greenhouses
  • Weather stations
  • Attics
  • Wine cellars
  • Server rooms
  • Cold storage rooms
  • Storage facilities
  • …and many more!

Once connected to a network, you can access the temperature sensor’s setup and control pages on a web browser where you can adjust the settings, or view the current temperature on the XW-110 Plus’ control page.

Live Demo With One of Our Sales Engineers

Let’s make it easy with a live demo and screen sharing.

Set up a one-on-one Q & A with one of our experts. We’ll help you find the best solutions for your next project and walk you through a demonstration.

XW-110 Setup

The diagram illustrates how this demonstration is wired. Nothing is connected to the relay contacts; however, you can still turn the relay on and off to see how it works. The input state only changes when a voltage is applied to the input. For this demonstration, we have connected one of our X-332 controllers to the input of the XW-110. You can apply a voltage to the input of the XW-110 by accessing the control page for the X-332 (Digital Input Control Page).

Important Information

  • Multiple users may be accessing this device simultaneously so the device can change while you are using it.
  • This unit will be reset to factory defaults daily at 2:30AM MST.
  • Please DO NOT change network or password settings.
