The IMI220-420A001 module is used to control 8 12 bit analog inputs with a working range from 0 to +10V. The inputs are of differential type to guarantee a high degree of immunity from disturbances; the voltages read on the input are transformed into quote.
Two interrupt quote can be defined for each input (one quota for the greater than or equal to comparison and the other for the less than or equal to): the operating system automatically returns the state of the greater than or equal to and less than or equal to markers for the entered quote.
External coding: 7, 9, 10.
Connection: by means of: IMI220-420A001 (20 pin 5.08 mm connector).
Use: more than one IMI220-420A001 module can be installed on the bus; this module can be optional.
Configuration parameters: module code and revision, identifier.
