QJ71BR11 Mitsubishi Universal model Redundant Power Supply Module
QJ71BR11 Overview
The QJ71BR11 is a MELSECNET/H network module manufactured by Mitsubishi Electric, designed for the Q series PLC systems. It facilitates high-speed data communication between programmable logic controllers (PLCs) and remote I/O stations, supporting both PLC-to-PLC networks (control/standard stations) and remote I/O networks (remote master stations). This module utilizes cost-effective coaxial cables for reliable industrial automation applications, enabling seamless integration into large-scale control systems
.
QJ71BR11 Key Features
High-Speed Communication: Operates at a transmission speed of 10 Mbps, ensuring efficient data exchange for real-time control applications
.
Dual Network Support: Functions in both PLC-to-PLC networks (control/standard stations) and remote I/O networks (remote master stations), enhancing system flexibility
.
Coaxial Cable Connectivity: Uses 75Ω coaxial cables (3C-2V/5C-2V types), reducing wiring costs compared to optical fiber systems while maintaining noise resistance
.
Scalable Architecture: Supports up to 32 stations per network (1 master station + 31 standard stations) and allows 4 modules to be installed per CPU, accommodating expansive industrial networks
.
Large Data Capacity: Handles substantial I/O points, including 8,192 LX/LY points (MELSECNET/10) or 16,384 LB/LW points (MELSECNET/10H), with a maximum data transfer capacity of 2,000 bytes per station for general and low-speed cyclic communication
.
QJ71BR11 Material and Applications
The module employs industrial-grade electronic components and connectors compatible with 75Ω coaxial cables (3C-2V/5C-2V). Its housing is designed for durability in harsh environments, typical of factory automation systems. Primary applications include:
Factory Automation: Integrating PLCs and remote I/O devices in manufacturing lines.
Process Control: Enabling real-time data exchange between control systems in chemical, electronic, and automotive industries
.
Energy Management: Monitoring and controlling distributed I/O points in utility systems
.
