QCS-21146E
Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.
The QCS-21146E 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-21146E 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
- Supports 12 BACstat network sensors for room sensing and control or 2 Field Modules for I/O expansion
- Fully programmable in GCL+
- 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 output, power, CPU and SCAN status
Applications
The QCS-21146E 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 QCS-21146E can be tailored to specific applications by creating and modifying BACnet objects and GCL+ programs.
