Triconex 3664 TCM Triple Communication Module Tricon SIS Safety System

Triconex 3664 TCM (Triple Communication Module) is a redundant fault-tolerant communication module for Schneider Tricon SIS safety instrumented system. It adopts triple modular redundant TMR architecture to establish reliable data exchange between Tricon controller and external DCS, SCADA and other host systems.

This module comes with dual Ethernet ports for network redundancy, supporting Modbus TCP protocol. It maintains safety data integrity and prevents single network point failure. It supports hot swap and comprehensive self-diagnosis, widely used as spare parts for oil, gas and chemical plant ESD and fire&gas safety cabinet maintenance.
