Product Description
The DSC-1280 is a fully programmable, Native BACnet
Building Controller that communicates on Twisted Pair
Ethernet 10-BaseT using BACnet IP and BACnet over
Ethernet, or on an RS-485 LAN using the BACnet MS/TP
protocol.
The controller includes an easy to mount enclosure and is
designed for a wide range of applications requiring no more
than 12 inputs and 8 outputs, including but not limited to Roof
Top Units, Air Handlers, Boilers or Chillers, etc. A second RS-
485 port may be configured as an MS/TP SubLAN or a
LINKnet network that supports up to 12 Delta BACstats or
other Delta LINKnet controllers.
