QCA-223 Application Controller

COSYS Building Controls

QCA-223

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

The QCA-223 Application Controller 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 designed for a wide-range of applications that have small local I/O requirements. It also supports BACstat® and other LINKnet devices

Features

  • Fully programmable in GCL+
  • Supports 4 BACstat network sensors on LINKnet for room sensing and control or 2 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
  • Supports Modbus capability via flash loading in the field
  • Service port
  • Screw or DIN rail mountable
  • LED indicator for each output, power, CPU and SCAN status

Applications

The QCA-223 is suitable for controlling various packaged units and equipment with small I/O requirements such as Fan Coil units, Unit Ventilators and Heat Pumps.
 
The fully programmable QCA-223 can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.
