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.
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.
