ICS Triplex T9831 Analog Input Termination Assembly

Technical Overview

• Primary Function: The ICS Triplex T9831 is a high-integrity Analog Input Termination Assembly (TA) designed to facilitate the secure connection between field-side sensors and the Trusted™ controller environment.

• Problem Solved: It streamlines the termination of 16 analog input channels, providing a centralized interface that filters out electrical noise and protects the internal control logic from external voltage transients.

• System Reliability: By incorporating robust optocoupler isolation and transient protection, the T9831 ensures that analog signal data remains stable and accurate, even in electrically noisy industrial settings like refineries and power plants.
