Web-Enabled 1-Wire Bus Module 64 Temp-Ch 9-28Vdc/P


The X-406-E and the X-406-I each offer four 1-Wire buses for up to 64 sensors, and a built-in web-server.


A Simple Solution for Large-Scale Temperature and Humidity Monitoring

The X-406-E is a fully-featured, web-enabled temperature and humidity monitoring and reporting module with four, independent 1-Wire Buses.

  • Each of the 1-Wire Bus inputs supports up to 16 sensors, for a total of up to 64 sensors.
  • There is no software required, no programming necessary, and no subscription to buy.
  • Simply web browse or use the app over WiFi or via the Cloud
  • The X-406-E requires PoE and/or 9 to 28Vdc
  • The X-406-I is the same except only operates on 9 to 28Vdc
  • See application TAB.

Industrial Internet of Things (IIoT)

The X-406-E or the X-406-I version are superb for any applications which require many 1-Wire sensors or isolation between sensors. For example:

 Server Room Monitoring

The X-406 is a very useful tool for monitoring server temperatures.

 Connect up to 64 Sensors

The X-406 features four 1-Wire Buses, making it optimal for monitoring the temperature of multiple servers. Each 1-Wire Bus can support up to 16 sensors for monitoring a total of up to 64 different server temperatures.

 Peer to Peer Communication

Link the X-406 to other ControlByWeb products for additional monitoring and control.

 Logging/Email Alerts

Enable logging to keep a real-time record of server temperatures over time. The X-406 can be configured to send custom email/text alerts if the sensor goes out of range.
