Control Solutions’ AddMe IIIfeatures 18 universal inputs which are context sensitive. When configured as an analog input, the continuously self-calibrating sigma-delta converter produces 15-bit resolution with high noise immunity. When configured as a discrete input, the converter switches to 8-bit resolution at 128 samples per second for fast response. All I/O points are accessed as BACnet objects.

Analog Input objects provide data from the analog I/O points. Linearization tables are provided for 10K and 20K type II, III, and IV thermistors. Input type and scaling is configured by writing to object properties. Analog and Binary Output objects provide BACnet access to the outputs. An additional 60 writeable Multistate Input objects are available for use by the user's program.
