Our COSYS Application and System Controls work along with our enterprise software platform OspreyFMS to provide a meaningful context.
The QCS-1212 is a fully programmable, Native BACnet® Building Controller that communicates on a 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-1212 also supports an additional BACnet MS/TP SubLAN for VAV and other application controllers. It is designed for a wide-range of applications that have mid-sized I/O requirements. The SubLAN may be configured to support BACstats and other LINKnet I/O devices.
- Native BACnet firmware
- BACnet MS/TP communications BACnet IP capability
- BACnet over Ethernet capability Integrated housing
- 12 Universal Inputs and 12 Universal Outputs
- Fully programmable in GCL+
- Application database and firmware can be flash loaded over the network
- Supports Modbus® capability by flash loading in the field via hardware key
- Hand/Off/Auto (HOA) switches with position feedback
- Tri-color LEDs to indicate output status
The QCS-1212 controller is suitable for controlling equipment such as AHUs, boilers, chillers and a variety of HVAC control systems.
Because of its programming capability, the QCS-1212 can be used to create or modify GCL+ programs and BACnet objects for specific applications.
