Overview
The ICS Triplex T8431 is a Trusted TMR analog input module engineered for high-reliability industrial applications. Moreover, its fully triplicated architecture ensures fault-tolerant operation, minimizing downtime and improving system availability. The module interfaces with 40 sourcing field input devices, providing configurable thresholds and precise analog monitoring. In addition, on-board diagnostics and Sequence of Events (SOE) reporting enable accurate and timely tracking of input states across all channels.
Key Features
- Triple Modular Redundancy (TMR): Each input channel incorporates full TMR for enhanced reliability.
- Comprehensive Diagnostics: Includes self-tests and automatic line monitoring to detect open and short circuits.
- Opto/Galvanic Isolation: Withstands 2500 V impulses for robust electrical isolation and system protection.
- Sequence of Events Reporting: SOE resolution of 1 ms with timestamp accuracy ±10 ms for precise tracking.
- Hot Replacement: Supports online module replacement using Companion Slot or SmartSlot configurations.
- Front Panel Indicators: LEDs display channel status, field wiring faults, and overall module health.
- Safety Certification: TÜV IEC 61508 SIL 3 certified for demanding industrial applications.
