T8431CX Product datasheet 

T8431CX Functional Description 

The ICS Triplex T8431CX Analog Input Module is a Triple Modular Redundant (TMR) 24Vdc analog input module designed for mission-critical industrial applications requiring SIL3 certification and fault-tolerant operation. Featuring 40 independent TMR channels, this module acts as a current sink for field devices while performing comprehensive diagnostics on each input. The DigitalInput Module T8431CX ICS Triplex excels in harsh environments with 2500V opto-galvanic isolation and advanced line-monitoring capabilities to detect open/short circuits per channel. Its robust architecture ensures continuous operation even during component failures.

Engineered for process control systems in oil & gas, power generation, and chemical plants, the Analog Input Module T8431CX ICS Triplex supports 1ms-resolution Sequence of Events (SOE) reporting with configurable voltage thresholds. Front-panel LED indicators provide real-time channel status and fault alerts, while the module's hot-swappable design (via Companion/SmartSlot) enables maintenance without system shutdown. Weighing just 1.149kg, the compact ICS Triplex T8431CX integrates seamlessly into existing racks while maintaining Rockwell Automation's Trusted® platform standards.

The Rockwell ICS Triplex T8403CX Trusted TMR 24VDC DigitalInput Module delivers unmatched reliability through its TMR voting architecture, where three independent signal paths cross-validate inputs to eliminate single-point failures. Compliant with IEC 61508 SIL3, it's ideal for safety instrumented systems (SIS) requiring <1% downtime. The module's 24Vdc power compatibility and flexible configuration options allow integration with diverse sensors across temperature, pressure, and flow measurement applications.

As part of Rockwell Automation's Trusted family, the Trusted TMR 24VDC DigitalInput Module T8431CX Rockwell comes with global technical support. Its combination of TUV-certified safety, millisecond SOE resolution, and predictive diagnostics makes it a future-proof solution for critical infrastructure protection. For industries demanding zero-compromise reliability, this module sets the benchmark for fault-tolerant analog input systems.
