1. Product Overview

TRICONEX RO3451 is a switch output module in the Invensys Triconex safety control system. It is specially designed for industrial automation environments and is used to process digital signals to control the start, stop or state switching of equipment. Its core features include high reliability, anti-interference ability and modular design, and it is suitable for safety-critical systems such as emergency shutdown systems (ESD), fire detection systems (F&G), etc.

2. Core Functions and Features

Anti-interference design

Shielded cables, partial shielding of PLC and high-voltage discharge components are adopted to effectively suppress the interference of power and signal lines.

Supports multiple wiring methods (such as twisted-pair wires and shielded wires), and is suitable for complex industrial scenarios.

(2) Modularity and maintainability

Hot-swappable design: Supports online replacement of faulty modules to reduce downtime.

Diagnostic function: Built-in LED status indicator light, providing real-time feedback on the health status of the module (such as communication abnormalities or hardware failures).

(3) Redundancy and scalability

It can be integrated into the Triconex Triple Module Redundancy (TMR) architecture and supports seamless expansion with other Triconex components, such as the main processor and communication modules.

Suitable for host racks or expansion racks, it supports a system scale of up to 15 racks at most
