QJ72LP25G Mitsubishi Universal Model Redundant Power Supply Module 5 V DC/3 A

QJ72LP25G Description 

QJ72LP25G Key Features

• Optical Duplex Loop Network: Dual-loop fiber topology with automatic path switching for fault tolerance; ensures uninterrupted communication even if one fiber segment fails.
• High-Speed & Large Capacity: Fixed 10 Mbps transmission speed; supports up to 65 stations per network (1 master + 64 remote I/O stations) and max total link points: LX/LY 8192 points, LB/LW 16384 points.
• Long-Distance Transmission: Max total network length up to 30 km, max inter-station distance up to 2 km using GI-50/125 optical fiber, ideal for large-scale plant-wide automation.
• Robust Communication Protocol: Uses HDLC frame format, NRZI encoding, frame synchronization, and CRC-16 error checking for high data integrity and noise immunity.
• Flexible Data Link: Supports remote master ↔ remote I/O, master ↔ sub-master data exchange; max link data size up to 2000 bytes per direction for bulk data transfer.
• Compact & Easy Installation: Standard Q Series module size, plug-and-play into Q Series base units; no external power required (draws 5 VDC from base unit).
• Industrial Reliability & Compliance: Wide operating temperature, anti-vibration/shock resistance; certified to UL, cUL, CE (EMC/RoHS), KC, and marine standards (LR, DNV, ABS) for global deployment.
• Built-In Diagnostics: Real-time network status monitoring, fault detection, and auto-recovery to minimize downtime.

QJ72LP25G Materials & Applications

Materials

• Housing & Frame: High-strength flame-retardant reinforced engineering plastic (UL94 V-0) with aluminum alloy shielding for electromagnetic interference (EMI) protection.
• Circuit Board: Multi-layer FR-4 PCB with surface-mount industrial-grade components, conformal coating for dust, moisture, and chemical resistance.
• Optical Interface: Precision 2-core fiber optic connectors (F06/F08, JIS C5975/5977 compliant) with low insertion loss and high durability.
• Internal Components: High-speed optical transceivers, industrial microcontroller, isolated communication circuits, and surge protection devices for stable fiber transmission.
• Terminals: Nickel-plated copper connection terminals for secure, corrosion-resistant electrical contact with the PLC base unit.

Typical Applications

• Large-Scale Factory Automation: Distributed I/O control for automotive assembly lines, steel mills, chemical plants, and power generation facilities.
• Long-Distance Process Control: Oil/gas pipelines, water treatment plants, port logistics, and mining systems requiring remote I/O over extended distances.
• Marine & Offshore Systems: Shipboard automation, offshore drilling platforms, and port cranes (compliant with marine certification standards).
• Material Handling & Logistics: Automated warehouses, conveyor systems, sorting lines, and heavy-duty crane control networks.
• Power & Energy: Substation monitoring, wind/solar farm control, and power distribution automation with distributed sensor/actuator networks.
• Heavy Machinery & Manufacturing: Large machine tools, printing/packaging lines, and textile mills with distributed I/O nodes.
