WiFi Controllers

Our new cellular monitoring and control modules make your life easier. When you need to deploy an IoT controller where no wired networking infrastructure exists, skip the third-party program hardware and build from our popular X-400 platform - now with embedded cellular connectivity. Remote monitoring and control has never been easier.

WiFi-Enabled PLCs

Remote Monitoring Made Easy

Our new WiFi-enabled monitoring and control modules make your life easier by providing you with extra networking flexibility. When you need to deploy an IoT controller where ethernet wiring would be inconvenient, choose our WiFi-Enabled I/O modules. Remote monitoring and control has never been easier.

  • The X-410W is ideal for creating remote monitoring and control systems that require WiFi connectivity and/or cloud access. With four relays and 4 digital inputs, the X-410W is the perfect solution for dozens of application. From access control to temperature monitoring, to lighting automation. it’s used in industries far and wide for stand-alone controls, as a capable RTU, or as a sophisticated edge programmable controller. It’s the ideal industrial IoT device.
  • The X-401W is perfect for simple input monitoring and relay control. This controller offers two Form-C relays, perfect for controlling low-voltage lights, motors, locks, solid-state relays (connected to larger loads), and more.
  • The FridgeAlert is purpose-built for commercial refrigeration monitoring. Whether it’s a cooler, freezer, or any temperature controlled area, you can monitoring up to 10 temperature sensors with a convenient touch screen display. This device also comes with WiFi and cellular versions to simplify networking and enable monitoring in difficult locations.

The Benefits of WiFi

  • Flexibility: WiFi-enabled PLCs are often used when a hardwired Ethernet connection isn’t feasible. It may be impossible to pull or install wire in an existing structure, for example.
  • Cost: With WiFi, integrators can avoid the expense of burying a line, channeling Ethernet cables, and installing other physical components.
  • Ease of Installation: Our WiFi-enabled PLCs can be assigned network credentials through the built-in interface. Then, all the module needs is power and you’re ready to go.

Cloud Compatible

The ControlByWeb Cloud simplifies monitoring, control, and data logging. It provides access to your controller but keeps logic on the device so you are not dependent on network connectivity. Get the best of both worlds with our reliable platform.
