COSYS Building Controls

QCA-V403E

Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.

The QCA-V1304E is a fully programmable, Native BACnet® Advanced Application Controller that communicates on Twisted-Pair Ethernet 10-BaseT using BACnet IP and BACnet over Ethernet. This controller is specifically designed for VAV applications and supports a RS-485 subLAN of smart network sensors and I/O expansion modules.

Features

  • Native BACnet firmware
  • Fully programmable
  • BACnet IP/BACnet over Ethernet Main LAN communications
  • Supports a RS-485 subLAN of smart network sensors and I/O expansion modules
  • Direct Mount housing integrates controller, damper actuator and airflow sensor into a single package for easy, cost effective installation
  • Firmware upgrade and database load/save over the network
  • LED status indicators of outputs, communication ports and CPU Scan Status
  • Optional field upgrade to Modbus® RTU with hardware key
  • Service port
  • Local Trending and Alarming

Applications

The QCA-V1304E is designed for VAV applications and includes an on-board actuator and true differential pressure sensor in a direct mount integrated housing.

The fully programmable QCA-V1304E allows GCL+ programs and BACnet objects to be tailored to any VAV application.
