Product Description


ICS Triplex T8431 Trusted TMR 24 Vdc Analog Input Module
40-Channel TMR Analog Input Module for Safety-Critical Industrial Process Monitoring
1. Product Overview

The ICS Triplex T8431 is a Trusted TMR (Triple Modular Redundant) 24 Vdc Analog Input Module, a key component of Honeywell Process Solutions' Trusted safety instrumented systems (SIS) and distributed control systems (DCS). It provides 40 TMR input channels to interface with sourcing field devices, acting as a current sink for accurate signal acquisition. With TMR architecture, 2500V opto/galvanic isolation, and comprehensive diagnostics, it ensures fault tolerance, high accuracy, and reliable monitoring in oil & gas, chemical, power generation, and other high-risk industrial processes, supporting safety-critical data collection and control.
