TRICONEX 2351 Analog Input Module

TRICONEX 2351 is an analog input module designed for Tricon triple modular redundant safety instrumented system. It collects 4-20mA analog signals from field transmitters for temperature, pressure, flow and liquid level measurement in safety critical processes.

This module adopts TMR triple voting fault-tolerant design with high signal precision and continuous channel self-diagnosis. It supports HART communication on the current loop and online hot swap, widely used as spare replacement for petrochemical, power and chemical safety control cabinet maintenance and upgrade projects.
