DAC-633E

The DAC-633E is a fully programmable, Native BACnet™ Advanced Application 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. It is designed for a wide-range of applications that have small local I/O requirements. It also supports BACstats and other Delta LINKnet devices.

Application

The DAC-633E is suitable for controlling various packaged units and equipment with small I/O requirements such as Fan Coil units, Unit Ventilators, Heat Pumps, and small Boilers or Chillers. The fully programmable DAC-633E can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.

Features

  • Native BACnet firmware
  • Fully programmable in GCL+
  • BACnet MS/TP communications (DAC- 633), BACnet/IP and BACnet Ethernet (DAC-633E)
  • Super Capacitor for real-time clock and SRAM backup (requires no maintenance) on DAC-633E
  • Supports 6 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 (can be powered internally or from an auxiliary transformer)
  • Firmware upgrade and database load/ save over the network
  • Supports Modbus capability via flash loading in the field
  • Service port
  • Screw or DIN rail mountable
