Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.
The QCA-V223 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 LINKnet I/O. The damper actuator assembly is available with or without position feedback. Additional inputs and outputs can be configured as required.
Features
- Native BACnet firmware
- BACnet MS/TP communications
- Supports 4 BACstat network sensors on LINKnet for room sensing and control or 2 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) - Fully programmable in GCL+
- True differential pressure sensor
- LED indicator for each output, communication port and SCAN status
- Application database and firmware can be flash loaded over the network
- Optional field upgrade to Modbus® RTU with hardware key
- Service port
Applications
The QCA-V223 is an application-specific controller for VAV and includes an actuator and true differential pressure sensor with integrated housing.
The fully programmable QCA-V223 allows GCL+ programs and BACnet objects to be tailored to any VAV application.
