8984 | Triconex Fault-Tolerant Network Module for Controllers

Product Description

Overview

The Triconex 8984 is a robust communication module designed for Triconex Safety Instrumented Systems (SIS).
It provides reliable network connectivity between Triconex controllers and external automation systems.
Moreover, the module features Triple Modular Redundancy (TMR) to maintain uninterrupted operation under hardware failures.
It ensures SIL 3 safety compliance and supports mission-critical applications in oil & gas, chemical, and power industries.

The 8984 module enables seamless integration with Distributed Control Systems (DCS), Human-Machine Interfaces (HMI), historians, and other automation platforms.
Therefore, it is essential for maintaining continuous communication in high-hazard industrial processes.
