4 Relays
WebRelay-Quad™ is used by many different companies for hundreds of applications such as industrial control, security, remote control, remote reset, and much more. It has four low-signal relays that can individually switch up to 3-Amp at 28V
X-WR-444CW: Cellular-Enabled I/O for Remote Monitoring

Wide Carrier Coverage
eUICC (eSIM) technology allows ControlByWeb cellular devices to operate across multiple carriers. This allows us to optimize cellular coverage based on your location.

No WiFi Necessary 
Cellular simplifies your installation and fits where no wired infrastructure exists. There’s no need for third-party resources or IT intervention—everything you need from a PLC is included with the X-WR-444CW.

Primary or Backup
With the X-WR-444CW, you have the option to use Ethernet as the primary connection to the network and cellular as a failover. This allows logging, remote access, and email alerts even if Ethernet fails.

Built-In Connectivity
The X-WR-444CW includes an omnidirectional antenna for use with the embedded LTE-M cellular radio. The antenna is FCC compliant and will not cause interference when installed correctly.

Configurable Status Page
The X-WR-444CW is powered by a lightweight, built-in user interface. Cellular devices have additional settings within the UI where users can review their signal strength, see registration status, set cellular mode and ping interval, and more.
