X-404 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 X-404. You can apply a voltage to the input of the X-404 by accessing the control page for the X-332 (Digital Input Control Page).
