Relay
A dual low-voltage signal relay is built into
the OME-RX21 for control of devices such
as electric screens and display lifts. A 3-pin
captive screw connector has been included
for connection.
When using a dual signal relay with an electric
projection screen, it allows for two dierent
circuits to be controlled: up and down
(pictured to the right).
The relay will default to follow the display. When
the unit turns on the relay will close C1 and
open C2. When the display is turned o and
signal is no longer being received C1 will open
and C2 will close.
There are 3 connections for the relay: C1, COM,
and C2 (Circuit 1, Common, and Circuit 2.)
