TRICONEX PLM3900N 

Overview

The TRICONEX PLM3900N is a high-performance logic module based on Triple Modular Redundancy (TMR) design, designed for industrial automation and process control systems. It delivers high reliability, precision, and redundant architecture, ensuring stable operation in harsh environments while maintaining system safety and stability.

Key Parameters

-

Product Features

• High Reliability: TMR architecture ensures continuous operation even if a single component fails.
• Redundant Design: Includes overcurrent, overvoltage, and undervoltage protection for stability under abnormal conditions.
• Scalability: Compatible with other TRICONEX modules for seamless system integration and expansion.
• Data Transmission: Supports Modbus registers and coils, with register lengths of 1, 8, or 16 bytes.
• Control Functions: Operates control blocks or SFC programs to reset internal counters or restore initial states.

-

Structure & Components

• Modular Design: Easy installation and maintenance.
• Communication Interfaces: Modbus, RS-232, RS-485, EtherNet/IP, etc.
• Redundant Protection Circuits: Independent circuits per I/O channel for high fault tolerance.
• Isolation & Power Amplification: Each output channel features isolation and amplification for stable signal transmission.

-

Applications

• Industrial Automation: Production line control, equipment monitoring, and process management.
• Safety-Critical Systems: Emergency Shutdown (ESD), Burner Management (BMS), oil & gas, chemical, power, transportation, and nuclear industries.
• Data Acquisition & Control: Converts sensor signals into control commands for precise external device control.
