  • Simple Web-Based Dashboard
  • No-Code Logic Builder
  • Peer-to-Peer Communication
  • Ethernet I/O Monitoring & Control
  • 400 Series Platform
  • Failover From Ethernet (X-400C Only)

X-400 Applications

  • Building Automation & Access Control
  • Process Control
  • Remote/Field Monitoring & Control
  • Dry Contact Monitoring/Notifications

Double the Coverage

Intelligent dual SIM technology allows ControlByWeb cellular devices to connect to the best network available. The X-400C will automatically switch networks as needed to maintain a strong connection.

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-400C.

Primary or Backup

With the X-400C, 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.

Power Your Whole Setup

Expansion modules have a ribbon-cable expansion bus that allows for shared I/O among ControlByWeb devices. It only requires one cellular-enabled PLC to enable all connected I/O to operate wirelessly.

Built-In Connectivity

The X-400C 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-400C 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.
