DSC-2424E System Controller 24 IO

The DSC-R2424E is a fully programmable, Native BACnet™ Building Controller replacement for the Intelli-Con Turbo Panel. It communicates using BACnet IP, BACnet over Ethernet or on an RS-485 LAN using the BACnet MS/TP protocol. The DSC-R2424E shares the same physical footprint, I/O expansion cards, and Zone Controller Protocol as the Intelli-Con Turbo.


The DSC-R2424E is suitable for controlling equipment such as AHUs, Boilers, Chillers and a variety of HVAC control systems. Because of its programming capability, the DSCR2424E can be used to create or modify GCL+ programs and BACnet objects for specific applications.
