General

The DAC-1180 is a fully programmable, Native BACnet® Advanced Application

Controller that either communicates on Twisted-Pair Ethernet 10-BaseT using BACnet

IP and BACnet over Ethernet (DAC-1180E) or an RS-485 LAN using the BACnet MS/TP

protocol (DAC-1180). It is designed for a wide-range of applications that have medium

local I/O requirements. It also supports BACstat® and other Delta LINKnet devices.

Features

• Fully programmable in GCL+
• Super Capacitor for real-time clock and SRAM backup which requires no maintenance (DAC-1180E)
• Supports 10 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
• Optional field upgrade to Modbus® RTU with hardware key
• Service port
• Screw or DIN rail mountable
• LED indicator for each output, power, CPU and SCAN status
