DVC-V304

The DVC-V304 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 specifically designed for VAV applications and supports the Delta BACstat and LINKnet I/O. The damper actuator assembly is available with or without position feedback. Additional inputs and outputs can be configured as required.

Application

The DVC-V304 is an application-specific controller for VAV and includes an actuator and true differential pressure sensor with integrated housing. The fully programmable DVC-V304 allows GCL+ programs and BACnet objects to be tailored to any VAV application.

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
  • Integrated housing with damper assembly for easy, cost effective installation
  • Reliable industry standard actuator (with optional position feedback)
  • True differential pressure sensor
  • Completely 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
