DVCV322E BACnet over Ethernet VAV Controller

The DVC-V322E is a fully programmable, Native BACnet™ Advanced Application Controller that communicates on Twisted-Pair Ethernet 10-BaseT using BACnet IP and BACnet over Ethernet. This controller is specifically designed for VAV applications and supports a RS-485 subLAN of Delta LINKnet smart network sensors and I/O expansion modules.


The DVC-V322E is designed for VAV applications and includes an on-board actuator and true differential pressure sensor in a direct mount integrated housing.The fully programmable DVC-V322E allows GCL+ programs and BACnet objects to be tailored to any VAV application.
