The ICS Triplex 9432 is a high-integrity, triple-redundant (TMR) digital input module engineered for critical safety instrumented systems (SIS) in hazardous industrial environments. Part of Rockwell Automation’s Trusted® platform, this module provides SIL 3 (IEC 61508/61511) certified performance for emergency shutdown (ESD), fire and gas (F&G), and turbine protection systems. Designed with three independent input channels per point, the 9432 performs continuous hardware-based voting to detect and mask failures in real time, ensuring fail-safe operation in oil/gas platforms, power generation, and chemical processing. Its rugged construction withstands extreme temperatures (-40°C to +70°C), vibration (5g RMS), and EMI interference, delivering uncompromised reliability where single-point failures could lead to catastrophic consequences.
The module supports 16 galvanically isolated voltage or contact inputs (24V DC nominal) with configurable de-bounce filtering, enabling direct interface with field devices like pressure switches or solenoid valves. Integrated diagnostics monitor channel discrepancies, wire breaks, and off-normal voltages, while front-facing LEDs provide per-channel health status. For brownfield upgrades, the ICS Triplex 9432 seamlessly integrates with legacy Trusted® TMR controllers like the T8400, preserving existing infrastructure investments while meeting modern safety standards.

Main Features and Advantages
Ultimate fault tolerance: Triple-redundant architecture with hardware voting logic achieves >99.99% diagnostic coverage (DC). Single-channel failures are automatically masked without process interruption, maintaining SIL 3 integrity during faults.
Advanced diagnostics: Real-time per-channel discrepancy detection identifies sensor/field wiring issues within 10 ms. Integrated short-circuit protection (<35>
Seamless integration: Hot-swappable design allows module replacement without system shutdown. Auto-recognition firmware synchronizes with Trusted® controllers (T9432, T8461) upon insertion.
Cyber-resilient design: Hardware-enforced change control requires physical keyswitch authorization for configuration modifications, meeting IEC 62443 security standards.
Application Field
The ICS Triplex 9432 is deployed in:
Oil & Gas: Emergency shutdown (ESD) valve monitoring on offshore platforms (SIL 3)
Power Generation: Turbine overspeed detection in nuclear plants (10 ms response)
Chemical Processing: High-integrity level switches in HF alkylation units
LNG Terminals: Cryogenic temperature switch interfacing (-40°C environments)
Mining: Conveyor belt emergency stop circuits with vibration resistance
