1.4 Example Configurations and Applications

WebRelay-Quad™ is very versatile and can be used in many applications. Several basic
installation schemes are illustrated in this section.

1.4.1 Basic Setup

The illustration below shows a simple WebRelay-Quad™ application. The example shows how a
3-color industrial light tower can be controlled remotely over an Ethernet network. The three lights
are connected to three of the relays so each light can be controlled individually. The lights can be
connected directly to the relay contacts because they are low power lights (LEDs). The controller
can be a web browser, a custom control application running on a computer, a PLC, or an
embedded industrial controller. Commands are sent to WebRelay-Quad™ over the Ethernet
network using standard IP protocols so the controller can be placed physically next to the light
tower or a distance away.
