QJ71GP21S-SX Description

QJ71GP21S-SX Key Features

• 1 Gbps Gigabit Transmission: Ultra‑fast 1 Gbps data transfer for high‑volume, low‑latency cyclic and message communication.
• Fiber Optic Connectivity: 1000BASE‑SX multi‑mode fiber (GI) with dual LC connectors, supporting long‑distance, noise‑immune communication.
• Master/Local Station Support: Configurable as control (master) or normal (local) station for flexible network architecture.
• External Power Supply: Dedicated external power input reduces internal backplane load and improves electrical isolation.
• Large Link Data Capacity: LB: 32768 pts (4 KB); LW: 131072 pts (256 KB); LX/LY: 8192 pts each (1 KB).
• Extended Network Reach: Max. station‑to‑station distance 550 m; total network length up to 66,000 m (120 stations).
• High Node Scalability: Supports up to 120 stations (basic CPU) or 64 stations (high‑performance CPU) per network.
• Redundancy & Diagnostics: Duplex loop topology, automatic failover, and comprehensive RAS diagnostics for enhanced reliability.
• LED Status Indicators: PWR, LINK, TX/RX LEDs for real‑time monitoring of power, link, and communication status.
• Compact DIN‑Rail Mount: Standard form factor for easy integration into control cabinets.

QJ71GP21S-SX Materials & Applications

Materials

• Housing: High‑strength, flame‑retardant engineering plastic (ABS/PC blend) with reinforced ribbing for durability and electrical insulation.
• Internal PCB: Glass‑epoxy laminate with gold‑plated contacts and heavy‑copper traces for signal integrity and corrosion resistance.
• Connectors: Industrial‑grade dual LC fiber connectors for secure multi‑mode fiber termination.
• Optical Components: Class 1 laser transmitter (IEC 60825‑1) for safe, reliable optical signal conversion.
• Protection Circuitry: Surge suppressors, EMC shielding, and isolation barriers to mitigate electromagnetic interference.

Typical Applications

• Process Automation: High‑speed data exchange in chemical, water treatment, and energy plants requiring long‑distance, noise‑resistant communication.
• Manufacturing: Automotive assembly lines, semiconductor fabs, and packaging machinery with distributed control architectures.
• Distributed Control Systems (DCS): Interconnection of remote controllers for coordinated process management across large facilities.
• Smart Factory Infrastructure: Backbone communication for digital factories, linking controllers, HMIs, and I/O systems.
• High‑Reliability Networks: Applications requiring redundant communication, such as power generation and critical infrastructure.
