Description

The Triconex AI3351 is a high-reliability Analog Input Module engineered for the Triconex Triple Modular Redundancy (TMR) safety system. This module provides precise signal acquisition for critical process variables in high-demand industrial sectors such as oil and gas refineries, petrochemical plants, and large-scale power generation facilities. By utilizing TMR architecture, the AI3351 ensures continuous operation and data integrity even during internal hardware failures. Its integration into the safety loop facilitates real-time monitoring and emergency shutdown capabilities, significantly reducing unscheduled downtime and maintaining compliance with SIL 3 safety standards in hazardous environments.

Features

  • Triple Modular Redundancy (TMR) architecture for fault-tolerant operation.
  • 32 isolated analog input channels.
  • Supports 4-20 mA or 0-5 VDC input signal ranges.
  • 12-bit resolution for high-precision data acquisition.
  • Hot-swappable design for maintenance without system downtime.
  • Comprehensive self-diagnostics for A/D converters and internal power rails.

Applications

The AI3351 is designed for safety-critical applications where high availability and fault tolerance are mandatory. Typical installations include Emergency Shutdown Systems (ESD), Burner Management Systems (BMS), and Fire and Gas (F&G) monitoring in petrochemical and power generation plants.
