Note that the X-WR-441 models run the 400 Series firmware, while the X-WR-1R12 runs the previous firmware.

What's the difference? Both models use the same proven hardware. The newer X-WR-441 brings an improved user interface, no-code logic builder, security enhancements, and additional 400 Series features.

Why purchase the older model? If you need a simple web interface with no cloud access or custom control logic, the older X-WR-1R12 is for you.

WebRelay Series Setup and Programming Demo

WebRelay Setup

The diagram illustrates how this demonstration is wired. Nothing is connected to the relay contacts; however, you can still turn the relay on and off to see how it works. The input state only changes when a voltage is applied to the input. For this demonstration, we have connected one of our X-332 controllers to the input of the WebRelay. You can apply a voltage to the input of the WebRelay by accessing the control page for the X-332 (Digital Input Control Page). Important Info about devices resetting

Important Information

  • Multiple users may be accessing this device simultaneously so the device can change while you are using it.
  • This unit will be reset to factory defaults daily at 2:30AM MST.
  • Please DO NOT change network or password settings.
