Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.
The QCA-11146 Application Controller is a fully programmable, Native BACnet® Advanced Application Controller that either communicates on Twisted-Pair Ethernet 10-BaseT using BACnet IP and BACnet over Ethernet (QCA-6411E) or an RS-485 LAN using the BACnet MS/TP protocol (QCA-11146). It is designed for a wide-range of applications that have medium local I/O requirements.
Features
- Super Capacitor for real-time clock and SRAM backup which requires no maintenance (QCA-11146E)
- Supports 10 BACstat network sensors room sensing and control, or 2 Field Modules 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
- 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-11146 is suitable for controlling various packaged units and equipment with medium I/O requirements such as small air handling units, boilers, and chillers.
The fully programmable QCA-11146 can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.
