ICS TRIPLEX T8431 Trusted TMR Analog Input Module in stock

ICS TRIPLEX T8431 is a triple modular redundant analog input module for ICS Triplex Trusted TMR SIS safety instrumented system. It is the base version of T8431 series, equipped with 40 triplicated analog input channels to collect 4-20mA and 0-6VDC signals from field transmitters and sensors, delivering validated process data to safety controller.

This module adopts SIL3 safety certification and 2oo3 hardware voting architecture, supporting per-channel wiring fault detection and SOE event recording. It has conformal coating to resist dust and moisture in plant environment, widely used for safety cabinet maintenance, spare parts replacement and plant safety instrument system retrofit projects.
