Control Solutions’ AddMe III features 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 Modbus holding registers.

Floating point holding registers provide data from the analog I/O points. In addition, analog (universal) inputs are mirrored to integer registers and may be treated as on/off values. Linearization tables are provided for 10K and 20K type II, III, and IV thermistors. Input type and scaling is configured by writing to additional holding registers.
