General

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 BACstat® and other Delta LINKnet devices.

Features

• Fully programmable in GCL+
• 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 (24 VAC) 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 fieldService port
• Screw or DIN rail mountable
• LED indicator for each output, power, CPU and SCAN status
