Product Description
Universal model Redundant Power Supply Module QJ71FL71-T
QJ71FL71-T Description
The QJ71FL71-T is a high‑performance industrial network interface module for MELSEC‑Q Series automation controllers, compliant with FL‑net (OPCN‑2) Ver.2.00. It integrates 10BASE‑T/100BASE‑TX Ethernet connectivity to enable reliable, high‑speed data exchange between controllers, HMIs, and field devices. Ideal for distributed and scalable automation architectures, it supports both cyclic and event‑driven communication, making it suitable for manufacturing, process, and building automation systems requiring robust, long‑distance networking.
QJ71FL71-T Key Features
- Dual‑Speed Ethernet Support: 10BASE‑T (10 Mbps, half‑duplex) and 100BASE‑TX (100 Mbps, full/half‑duplex) for flexible network deployment.
- FL‑net (OPCN‑2) Ver.2.00 Compliance: Adheres to open industrial networking standards for multi‑vendor interoperability.
- IEEE 802.3 & UDP/IP FA Link Protocol: Meets global Ethernet standards with FA‑optimized protocol for industrial communication efficiency.
- Large Link Data Capacity: System‑wide max. 8 kbit + 8 kword; node‑max. 8 kbit + 8 kword; transient message max. 1024 bytes × 2 (Tx/Rx).
- Extensive Memory Areas: Error log (512 words), status (2 kbit/2 kword), local/remote node parameter, device profile, and message areas for comprehensive diagnostics.
- High Scalability: Max. 254 system nodes; cascade connection up to 4 stages (10BASE‑T) / 2 stages (100BASE‑TX).
- Hub‑to‑Node Distance: Up to 100 m for 10BASE‑T/100BASE‑TX, supporting flexible network topologies.
- Intelligent I/O & Diagnostics: 32 intelligent I/O points; comprehensive fault detection (link, overload, hardware) for reliable operation.
- LED Status Indicators: PWR, LINK, TX/RX LEDs for real‑time monitoring of power, link, and data transfer status.
- Compact DIN‑Rail Mount: Standard form factor for easy integration into control cabinets and existing Q Series systems.
QJ71FL71-T Materials & Applications
Materials
- Housing: High‑strength, flame‑retardant engineering plastic (ABS/PC blend) for electrical insulation and industrial durability.
- Internal PCB: Glass‑epoxy laminate with gold‑plated contacts for stable signal integrity and corrosion resistance.
- Connectors: Industrial‑grade RJ45 (8‑pin modular jack) for 10BASE‑T/100BASE‑TX Ethernet, ensuring secure, reliable connections.
- Protection Circuitry: EMC shielding, surge suppression, and isolation barriers to mitigate electromagnetic interference in harsh industrial environments.
Typical Applications
- Manufacturing Automation: Production line integration, connecting controllers, HMIs, and I/O systems across large facilities.
- Process Industries: Chemical, water treatment, and energy plants requiring long‑distance, noise‑resistant communication.
- Building Automation: Centralized control of HVAC, lighting, and security systems in commercial complexes.
- Distributed Control Systems (DCS): Interconnection of remote controllers for coordinated process management.
- System Upgrades: Retrofit of legacy FL‑net networks with modern Ethernet connectivity for enhanced performance.
