1.4.1 Basic Setup

The illustration below shows a simple WebRelay-Quad application. The example shows how a 3-color
TM
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
TM
physically next to the light tower or a distance away.
