Precision WiFi Digital Input

  • XW-111B,XW-111B+PS5VW1.0-2.5MM

The XW-111™ is an easy-to-use, wireless digital input monitoring device with a built-in web server. It can sense the state of up to two switch-state closure sensors.

  • 2 Digital Inputs
  • WiFi-Enabled (802.11 b/g/n)

The XW-111 monitors and reports the status of switch closure sensors and alarms. It’s ideal for applications where a device’s status must be monitored and Ethernet wiring is not accessible or practical to install. This could include push buttons, magnetic door alarm switches, micro-switches, or any device with a relay or switch closure output.

XW-111 Features

  • Input Status Monitoring
  • Built-In Web Server
  • Email Notifications
  • AC Power Failure Notification

Wireless Digital Input Applications

As a standalone device, the XW-111 is a great solution in applications where hard wiring isn’t practical or convenient. Some examples include:

  • Door Open/Close
  • Window Open/Close
  • Motor On/Off
  • Water Leak Detector
  • Mechanical Switch/Push-Button
  • Loop Detector

Once connected to a network, you can access the input’s setup and control pages on a web browser where you can adjust the settings or view the current input status on the XW-111’s control page.
