Triconex 4352B Communication Module

The Triconex 4352B Communication Module is an advanced industrial communication module designed specifically for Triconex Tricon® fault-tolerant safety systems. As an enhancement of the earlier 4352A model, the 4352B introduces improved diagnostics, enhanced protocol handling, and higher communication throughput, while maintaining seamless compatibility with existing Tricon platforms.

Engineered with Triple Modular Redundancy (TMR), the 4352B ensures uninterrupted communication between the Tricon controller and external systems, such as Distributed Control Systems (DCS), Human-Machine Interfaces (HMI), SCADA environments, and engineering workstations. It plays a critical role in real-time data exchange, command execution, and system diagnostics in mission-critical applications across a wide range of industrial sectors.

This module is a cornerstone for organizations implementing IEC 61508 SIL 3 safety systems, helping achieve high integrity and availability while supporting protocols like Modbus RTU, Modbus TCP/IP, OPC, and RS-232/RS-485 serial communication.
