Mixed connection of InteliLite analog inputs:
AI1
– binary input
AI2
– three state input
AI3
– analog resistive input
Hint:
Description of analog inputs with COM terminal and 4 pins relates to units with HW version 1.3. Older
HW versions do not have “COM” terminal and use only 3 pins AI1, AI2 and AI3.
