Overview

The Triconex 4352AN Communication Module (TCM) is a key component in Triconex safety and critical control systems, providing robust and secure communication for real-time data transfer. It consolidates multiple legacy communication functions into a single, high-reliability unit, thereby simplifying system architecture and improving maintainability.

Moreover, the 4352AN supports redundant configurations, ensuring continuous operation even during hardware faults. Designed for harsh industrial environments, it complies with IEC 61508 and is certified for SIL 3 safety applications. It facilitates communication between Tricon controllers, HMIs, DCS systems, and third-party PLCs through fiber optic and serial interfaces.

In addition, the module is hot-swappable, allowing maintenance and replacement without system interruption. Its durability and fault tolerance make it ideal for mission-critical systems in oil & gas, power generation, petrochemical, and process automation industries.

Technical Data

Typical Applications

• Distributed Control Systems (DCS): Enables secure, high-speed communication between Tricon controllers and supervisory systems.

• Emergency Shutdown Systems (ESD): Facilitates deterministic data exchange for fault detection and safety actuation.

• Oil & Gas Facilities: Interfaces with fire and gas systems and remote I/O nodes for rapid response.

• Power Generation Plants: Links turbine and boiler control systems with plant-wide monitoring platforms.

• Petrochemical Automation: Integrates safety logic and interlocks across multiple control layers.

Example:
In a refinery’s SIS, the 4352AN ensures real-time data transfer between the Tricon controller and external HMIs, maintaining operational visibility and system integrity even under abnormal conditions.
