QCS-0811
Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.
The QCS-0811 is a fully programmable, Native BACnet® Building Controller that communicates on Twisted-Pair Ethernet 10-BaseT using BACnet IP and BACnet over Ethernet, or on an RS-485 LAN using the BACnet MS/TP protocol. The QCS-0811 is designed for a wide-range of applications that have medium local I/O requirements. It also supports BACstat® and other LINKnet devices.
Features
- Fully programmable in GCL+
- Super capacitor for real-time clock and SRAM backup (requires no maintenance)
- Supports 12 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 auxillary 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 output, power, CPU and SCAN status
Applications
The QCS-0811 is suitable for controlling various packaged units and equipment with medium I/O requirements such as multiple-room reheat valves or small air handling units, boilers and chillers.
The fully programmable QCS-0811 can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.
