Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.
The QCA-1304 is a fully programmable, Native BACnet® Advanced Application Controller that communicates on Twisted-Pair Ethernet 10-BaseT using BACnet IP and BACnet over Ethernet (QCA-1304E) or an RS-485 LAN using the BACnet MS/TP protocol (QCA-1304). It is designed for a wide-range of applications that have small local I/O requirements.
Features
- Supports 4 BACstat network sensors for room sensing and control or 2 Field Modules for I/O expansion
- 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
- Fully programmable in GCL+
Applications
The QCA-1304 is suitable for controlling various packaged units and equipment with small I/O requirements such as fan coil units, unit ventilators, heat pumps, and small boilers or chillers.
The fully programmable QCA-1304 can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.
