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.
