TRICONEX AI3351 Analog Input Module in stock

TRICONEX AI3351 is a high-precision analog input module designed for Trident triple modular redundant safety instrumented system. It acquires 4-20mA analog signals from field transmitters for pressure, temperature, flow and liquid level measurement in safety-critical industrial processes.

This module adopts TMR triple voting fault-tolerant architecture with 16-bit high resolution sampling and built-in loop diagnostic function. It supports HART signal superimposition and online hot swap, widely used as spare replacement for petrochemical, power and chemical safety control cabinet maintenance and retrofit projects.
