The original WebRelay™ offers exactly what its name suggests, a web-controlled relay with a simple browser-based GUI. It is an electromechanical relay featuring a built-in web server and optically isolated input that can be used to monitor dry contacts or control industrial and commercial equipment.

1 Relay

1 Digital Input

Note that the original model runs older firmware with no cloud access, a simpler browser interface, and no programmable logic or data logging. If you want an updated model on the same great hardware, look at the new WebRelay with the latest 400 series firmware.

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.
