HIMA X-AI-32-01 32-Channel Analog Input Module

HIMA X-AI-32-01 is a 32-channel analog input module designed for the HIMax safety instrumented system. It collects 4-20mA analog signals from field transmitters and converts process measurements into digital data for safety logic processing.

This TÜV-certified SIL 3 module provides built-in loop power supply for field sensors and supports continuous channel self-diagnosis. It is widely used as critical spare parts for ESD, F&G and safety interlock systems in process industries.
