DAC-322
Description: 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.
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
Application: The DAC-322 is suitable for controlling various packaged units and equipment with small I/Orequirements 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.
Accessories:
- RPT-768—Delta Network Repeater for BACnet MS/TP
- TRM-768—Delta Network Terminator for BACnet MS/TP
- CON-768—Delta Network Converter
