Application
The DAC-633E is suitable for controlling various packaged units and equipment with small I/O requirements such as Fan Coil units, Unit Ventilators, Heat Pumps, and small Boilers or Chillers. The fully programmable DAC-633E can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.
Features
- Native BACnet firmware
- Fully programmable in GCL+
- BACnet MS/TP communications (DAC- 633), BACnet/IP and BACnet Ethernet (DAC-633E)
- Super Capacitor for real-time clock and SRAM backup (requires no maintenance) on DAC-633E
- Supports 6 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 (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 field
- Service port
- Screw or DIN rail mountable
