Product Description

Mitsubishi Universal model Redundant Power Supply Module QJ71MT91



QJ71MT91 Description


The QJ71MT91 is a high-performance MODBUS/TCP network communication module designed for modular industrial PLC systems. It serves as a critical communication gateway, enabling seamless data exchange between the host PLC system and a wide range of third-party MODBUS/TCP-compatible devices. This module supports both Master/Client and Slave/Server functionalities, allowing flexible integration into diverse industrial network architectures. Equipped with a 10/100 Mbps auto-negotiating Ethernet port, it facilitates reliable, high-speed communication over standard twisted-pair cabling, ideal for establishing stable connections in factory automation, process control, and distributed I/O systems.


 
QJ71MT91 Key Features

  • Dual Operational Modes: Simultaneously supports MODBUS/TCP Master (Client) and Slave (Server) functions for versatile network configuration.
  • High-Speed Ethernet Connectivity: Auto-detecting 10BASE-T/100BASE-TX port with RJ45 connector for fast, reliable data transmission.
  • Extensive Device Compatibility: Manages up to 64 MODBUS/TCP slave devices as a Master, supporting full protocol function codes.
  • Concurrent Command Execution: Capable of executing up to 8 dedicated MODBUS instructions simultaneously for efficient multi-device polling.
  • Large Data Handling: Supports up to 64k points each for coils, inputs, input registers, and holding registers.
  • Automatic Slave Response: Acts as a slave without requiring custom programming, automatically responding to up to 8 external master connections.
  • Robust Data Buffer: Internal I/O data area of 4k words for both input and output, ensuring efficient data buffering.
  • Industrial Environmental Rating: Wide operating temperature range and high resistance to shock and vibration for harsh environments.
  • Easy System Integration: Compact, rack-mountable design for seamless installation into standard PLC racks.
  • Comprehensive Status Monitoring: LED indicators for power, network link, activity, and individual communication status.
  • Global Certifications: Compliant with international standards including CE, UL/cUL, RoHS, and major marine certifications.
