Description
Product Overview
TRICONEX 4355X (TCM) is a TMR triple‑modular redundant communication module designed for Triconex Tricon SIS safety instrumented system. As the core TCM communication unit, TRICONEX 4355X delivers dual Gigabit Ethernet, galvanically isolated RS‑232/RS‑485 serial ports and SFP fiber expansion. TRICONEX 4355X supports Modbus TCP/RTU, TSAA, HART‑IP, SNTP time synchronization and multi‑protocol data exchange. TRICONEX 4355X enables reliable high‑speed communication between Tricon SIS and external DCS, HMI, third‑party field instruments. Hot‑swap capability guarantees non‑stop safety operation, widely deployed in oil & gas, petrochemical and power critical safety projects.
Key Features
