8 Channel DSI Gateway Range
Learn Enabled
The 8 channel DSI gateway units are DIN rail mounted units designed to control Atco-Tridonic brand dimmable
electronic ballasts featuring the digital serial interface. These DSI units feature learn mode, local and remote overrides
for on/o control, channel, C-Bus and unit status indicators.
Each DSI channel can drive up to 100 DSI ballasts allowing a total of 800 DSI ballasts to be connected to a single
C-Bus/DSI gateway module.
The DSI gateway is capable of detecting faulty lamps connected to its terminals and issuing a message onto the C-Bus
network. These messages can be read by C-Gate server application, when integrated as part of an overall building
management system, lamp status may be reported to a central location.
The DSI units are available as passive and current sourcing models that source up to 200mA to the C-Bus network.
