Output Units
Output units are C-Bus units which are used to control electrical loads.
Some loads that can be controlled by output units are:
lighting circuits
towel rails
curtain control motors
DSI electronic ballasts
infrared control.
Output units respond to the C-Bus messages that are generated by C-Bus
input units.

C-Bus Relays
C-Bus relay output units are available in a number of different DIN rail
enclosures for different purposes. All DIN rail relays are voltage free. This
allows the relays to be used in a range of different applications such as
lighting and fan control.
All DIN rail relay units (excluding the C-Bus Shutter Relay) are available
with or without an onboard 200 mA
C-Bus power supply. They can also provide a C-Bus clock and have a
software selectable network burden.
