DSC-1212
Description: The DSC-1212 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-1212 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.
Features:
- Native BACnet firmware
- BACnet MS/TP communications
- Optional BACnet IP
- Optional BACnet over Ethernet capability
- Integrated housing
- 12 Universal inputs and 12 Universal outputs
- Fully programmable in GCL+
- Application database can be flash loaded over the network
- Controller firmware can be flash loaded over the network
- Supports modbus capability by flash loading in the field via hardware key
- Optional Hand/Off/Auto switches with position feedback
- Tri-color LED’s to indicate output status
Application: The DSC-1212 is suitable for controlling equipment such as AHUs, Boilers, Chillers and a variety of HVAC control systems.
Because of its programming capability, the DSC-1212 can be used to create or modify GCL+ programs and BACnet objects for specific applications.
