DSC-1212E

DSC-1212E BACnet Building Automation System Controller

The DSC-1212E is a fully programmable, Native BACnet™ Building Controller that communicates on a 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 DSC-1212E also supports an additional BACnet MS/TP SubLAN for VAV and other application controllers.

It is designed for a wide-range of applications that have mid-sized I/O requirements. The SubLAN may be configured to support Delta BACstats and other Delta LINKnet I/O devices.

Application

The DSC-1212E is suitable for controlling equipment such as AHUs, Boilers, Chillers and a variety of HVAC control systems. Because of its programming capability, the DSC-1212E can be used to create or modify GCL+ programs and BACnet objects for specific applications.

Features:

  • Native BACnet firmware
  • BACnet MS/TP communications
  • BACnet IP capability
