DAC-322

BACnet Application Controller - Delta Controls

The DAC-322 is a fully programmable, Native BACnet™ Advanced Application Controller that communicates on an RS-485 LAN using the BACnet MS/TP protocol. This controller 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-322 is suitable for controlling various packaged units and equipment with small I/O requirements such as Fan Coil units, Unit Ventilators and Heat Pumps.

The fully programmable DAC-322 can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.

Features

  • Native BACnet firmware
  • BACnet MS/TP communications
  • Supports 4 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
  • Easy to mount housing
  • 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 via flash loading in the field
  • Supports flash loading Modbus upgrades via hardware key
  • Derived Network Addressing (DNA) for simple integration into a standard network architecture
  • Service port
