ICS TRIPLEX T9432 Trusted Analog Input Module

The ICS TRIPLEX T9432 is a high-performance analog input module developed for the Trusted TMR safety instrumented system. It adopts triple modular redundancy fault-tolerant architecture to continuously collect analog signals such as pressure, temperature and flow from field transmitters, converting analog measurements into digital data for safety controller processing.

This module supports standard 4~20mA analog input signals and provides comprehensive channel diagnostic functions. It meets SIL3 safety requirements and supports hot-swap operation without system shutdown, ensuring continuous safety monitoring. It is widely stocked as spare parts for plant safety system maintenance and technical renovation projects.
