QCA-0016 Application Controller

COSYS Building Controls


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

The QCA-0016 is a fully programmable, Native BACnet® Advanced Application
Controller that communicates on an RS-485 LAN using the BACnet MS/TP protocol.
The QCA-0016 is designed for monitoring, trending and alarming remote inputs.


  • Native BACnet firmware
  • BACnet MS/TP communications
  • Fully programmable in GCL+
  • Super Capacitor for real-time clock and SRAM backup which requires no maintenance (DAC-1146E)
  • Supports 4 network sensors on LINKnet for room sensing and control
  • 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
  • Optional field upgrade to Modbus® RTU with hardware key
  • Service port
  • Screw or DIN rail mountable
  • LED indicator for each output, power, CPU and SCAN status


The QCA-0016, with its 16 inputs, is suitable for monitoring the status of a wide variety if equipment and sensors. The controller board is capable of interfacing to 4-20 mA, 10 kΩ, 5 V, 10 V and dry contact inputs. Because of its programming capability, the QCA-0016 can be used to create or modify GCL+ programs and BACnet objects for specific  applications.
