ICS TRIPLEX T9432 Trusted Digital Input Module

The ICS TRIPLEX T9432 is a high-density, Triple Modular Redundant (TMR) digital input module engineered for safety-critical industrial applications, serving as a core component of the ICS Triplex Trusted™ safety system. Designed to capture and process discrete digital signals from field devices such as emergency stop buttons, limit switches, pressure sensors, and flame detectors, this module leverages TMR architecture to ensure fault tolerance and signal integrity—even in the event of single or dual hardware failures. It features 32 isolated digital input channels, each with built-in diagnostics to detect open circuits, short circuits, and signal degradation, providing real-time status feedback to the safety controller for proactive maintenance and system reliability. The T9432 is fully compliant with global safety standards including IEC 61508 SIL 3, ANSI/ISA S84.01, and EN 954-1 Category 4, making it ideal for deployment in oil and gas refineries, chemical processing plants, power generation facilities, and offshore drilling platforms. With its ruggedized industrial design, wide temperature tolerance, and hot-swappable functionality, the module minimizes unplanned downtime and ensures seamless integration into safety instrumented systems (SIS) and emergency shutdown (ESD) systems.

Important Note: The ICS TRIPLEX T9432 digital input module must be installed and configured by certified safety system engineers with expertise in ICS Triplex Trusted TMR systems. Proper wiring practices, including the use of shielded cables for signal transmission, are critical to minimize electromagnetic interference and ensure signal integrity in harsh industrial environments. Before commissioning, verify that the module’s input voltage configuration matches the specifications of connected field devices, and that all safety certifications align with site-specific regulatory requirements.
