Description
The ICS Triplex T8431C Trusted TMR Analog Input Module is a high-reliability input module designed for 24 Vdc systems within the Trusted™ control platform. Built using Triple Modular Redundancy (TMR) architecture, the T8431C delivers exceptional fault tolerance and dependable signal acquisition for safety-critical industrial applications.
This module supports up to 40 analogue input channels, allowing it to interface with a large number of sourcing field devices. Acting as a current sink for all connected inputs, the T8431C ensures stable and accurate signal measurement across a wide range of industrial sensors. It is well suited for industries such as oil and gas, chemical processing, power generation, and other environments where system availability and accuracy are essential.
The T8431C provides comprehensive diagnostics on each input channel, continuously monitoring signal integrity and module health. Its built-in line-monitoring capability detects open or shorted field cables, helping operators identify wiring issues quickly and reduce maintenance downtime. To support event tracking and system analysis, the module also includes onboard Sequence of Events (SOE) reporting with a resolution of 1 ms, enabling precise time-stamped event logging.
With high-resolution analog-to-digital conversion, fast update times, and precise time-stamping, the ICS Triplex T8431C ensures accurate real-time data acquisition and reliable system performance in demanding safety and control applications.
