Siemens Building Technologies (BT HQ CC OC)
The DF8000 unit is a flexible I/O system made up of DIN rail-mounted modules that can be combined in local units so as to concentrate from 4 to 48 I/O points, distributed on a RS-485 line.
DF8000 detects any input status change, and transmits this information to the supervising host. The individual outputs are controlled according to the commands sent by the supervising station. The communication line to and from the supervisor is fully monitored.
DF8000 can be used to interface technological signals or to interface with control panels.
