Relays Page:
The Relays page provides control and configuration of each of the eight relays. The relays are used to provide a low
or high impedance signal that may be used by a traffic controller or device as indication that a specific event or action
has taken place. They may also be used to switch on or off power to a device. Each relay has two mating contacts for
which to attach wiring and LED indicators to show when power to a relay is active.
