Description

The Triconex 3351 is a high-performance analog input module designed for integration into fault-tolerant safety instrumented systems. This module provides reliable signal acquisition, converting field-level analog inputs into precise digital data for processing within the Tricon safety controller. It is specifically engineered to support critical safety applications where continuous monitoring and high availability are required, such as in oil and gas, power generation, and chemical processing industries. By utilizing advanced diagnostics, the 3351 ensures that process variables are accurately captured while maintaining the integrity of the safety loop.

Features

• Supports 32 differential input channels for high-density signal monitoring.
• Designed for Triple Modular Redundant (TMR) safety architectures.
• Features integrated signal conditioning to filter noise and ensure accurate data conversion.
• Provides galvanic isolation to protect the backplane from field-side electrical disturbances.
• Continuous self-diagnostic routines to detect and report module health in real-time.

Applications

The 3351 module is intended for use in safety-critical environments requiring reliable monitoring of process transmitters. Typical applications include, but are not limited to, pressure, temperature, and flow monitoring in emergency shutdown systems (ESD), burner management systems (BMS), and fire and gas detection arrays.
