DSC-1146E
Description: The DSC-1146E is a fully programmable, Native BACnet™ Building Controller that communicates on an RS-485 LAN using the BACnet MS/TP protocol. The DSC-1146E is designed for a wide-range of applications that have medium local I/O requirements. It also supports BACstats and other Delta LINKnet devices.
Features:
- Native BACnet firmware
- Serial port for modem connection
- BACnet MS/TP communications
- Super capacitor for real-time clock and SRAM backup (requires no maintenance)
- Supports 12 BACstat network sensors on LINKnet for room sensing and control or 2 Delta Field Modules on LINKnet for I/O expansion
- Actuator power terminal (24VAC) for each analog output
- 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
- Derived Network Addressing (DNA) for simple integration into a standard network architecture
- Service port
Application: The DSC-1146E is suitable for controlling various packaged units and equipment with medium I/O requirements such as small Air Handling Units, Boilers and Chillers.
The fully programmable DSC-1146E can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.
Accessories:
- RPT-768—Delta Network Repeater for BACnet MS/TP
- TRM-768—Delta Network Terminator for BACnet MS/TP
- CON-768—Delta Network Converter
Ordering: DSC products with V3.30 firmware or later can not be flashed down to V3.22. To order product with V3.22 firmware append -V322 to the product name. Order the DSC-1146E with the desired options according to the following product numbers:
