DSC-1146E

DSC-1146E BACnet Building System Controller - Delta Controls Product

The DSC-1146E is a fully programmable, Native BACnet® Building Controller that communicates on 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-1146E is designed for a wide-range of applications that have medium local I/O requirements. It also supports BACstat® and other Delta LINKnet devices.

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.

Features

  • Native BACnet firmware
  • Fully programmable in GCL+
  • BACnet IP and BACnet over Ethernet communications
  • Super capacitor for real-time clock and SRAM backup which 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 (24 VAC) for each analog output (can be powered internally or from an auxillary transformer)
  • Firmware upgrade and database load/save over the network
  • Supports Modbus® capability by flash loading in the field via hardware key
  • Service port
  • Screw or DIN rail mountable
