DescriptionThe DSC-1146E is a fully programmable, Native BACnet™ Building Controller that communicates onTwisted-Pair Ethernet 10-BaseT using BACnet IP and BACnet over Ethernet, or on an RS-485 LANusing the BACnet MS/TP protocol. The DSC-1146E is designed for a wide-range of applications thathave medium local I/O requirements. It also supports BACstats and other Delta LINKnet devices.

ApplicationThe DSC-1146E is suitable for controlling various packaged units and equipment with medium I/O requirements such as small Air Handling Units, Boilersand Chillers.

The fully programmable DSC-1146E can be tailored tospecific applications by creating and modifying BACnetobjects and GCL+ programs.

Features—Native BACnet firmware

—Serial port for modem connection

—BACnet IP and BACnet over Ethernet 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 FieldModules on LINKnet for I/O expansion

—Actuator power terminal (24VAC) for each analogoutput

—Fully programmable in GCL+

—Application database can be flash loaded over thenetwork

—Controller firmware can be flash loaded over the network

—Supports Modbus capability by flash loading in thefield via hardware key

—Derived Network Addressing (DNA) for simple integration into a standard network architecture

—Service port
