QCA-FC223 Application Controller

COSYS Building Controls

QCA-6411-Application-Controller2

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

The QCA-FC223 is a fully programmable, Native BACnet® Advanced Application Controller that communicates on a RS-485 LAN using the BACnet MS/TP protocol. Direct 240 VAC line voltage terminal connections are provided for 1,2 or 3 speed fans. 

Features

  • Native BACnet firmware
  • BACnet MS/TP communications
  • Standalone operation or on BACnet
  • Fully programmable in GCL+
  • Pre-loaded fan coil application database
  • Direct connection to BACstat II (DNS-24 or DNS-24L)
  • 2 tri-state and 2 analog outputs for relay actuation
  • 3 relays rated for motor loads to control 1-, 2-, 3-speed fans, complete with interlocks and time delays for equipment protection
  • Slim design fits into narrow fan coil units
  • Power supplied by power mains
    (onboard 24 VAC transformer included)
  • Derived Network Addressing (DNA) for simple integration into a standard network architecture
  • Service port

Applications

The QCA-223 is designed for fan coil control. With 2 TRIAC outputs and 2 analog 0-10VDC outputs, it covers a wide range of fan coil unit applications.
The QCA-223 allows for sequence modifications as required by the design engineer or building owner. It provides simple, easy-to-install fan coil control solutions for office buildings, hotels or residential buildings.
