Analog Input objects provide data from the analog I/O points. Linearization
tables are provided for 3K, 10K and 20K type II, III, and
IV thermistors. Input type and scaling is confi gured by writing to
BACnet object properties. Additional uncommitted writeable objects
are available for data exchange with the user program.
Two of the analog/universal inputs can be confi gured as pulse
counting inputs. These inputs measure frequency, or totalize pulse
input at up to 5 kHz. The totalizing input has non-volatile count
storage. The count is stored to non-volatile memory every 15 minutes,
providing a 28-year life.
