Mitsubishi Universal model Redundant Power Supply Module QJ71LP21-25
QJ71LP21-25Description
The QJ71LP21-25 is a high-speed optical fiber network module designed for modular PLC systems, supporting both PLC-to-PLC network (control/normal station) and remote I/O network (remote master station) applications. It adopts a dual-loop optical fiber transmission structure, utilizing token ring communication protocol to realize reliable data exchange and distributed control over long distances. This module supports selectable communication speeds (25 Mbps/10 Mbps) and is compatible with multiple types of optical fiber cables, enabling flexible system networking and large-scale industrial automation interconnection. With compact dimensions and robust performance, it serves as a critical component for building stable, high-speed industrial optical communication networks.
QJ71LP21-25 Key Features
Dual-Loop Redundant Transmission: Adopts duplex loop optical fiber topology, ensuring uninterrupted communication even in case of single-point line failure.
High-Speed Communication: Supports 25 Mbps (max.) and 10 Mbps selectable transmission rates via mode switch, meeting high-speed data exchange requirements.
Flexible Network Modes: Operates in both MELSECNET/H and MELSECNET/10 modes, compatible with legacy and new-generation network systems.
Large Network Capacity: Connects up to 64 stations (1 control + 63 normal) for PLC networks, or 65 stations (1 remote master + 64 remote I/O) for I/O networks.
Long-Distance Transmission: Supports maximum total network distance of 30 km; compatible with SI, H-PCF, broadband H-PCF, and QSI optical fiber cables.
Massive Data Link Capacity: Supports up to 8,192 LX/LY points, 16,384 LB/LW points per network for large-scale data sharing.
Optical Isolation: Full electrical isolation between internal circuits and optical fiber interface, enhancing anti-interference and system safety.
Compact Design: Slim profile (27.4mm width) for high-density mounting in standard PLC racks, occupying only 1 I/O slot.
Built-in Diagnostics: Comprehensive self-diagnosis, error detection (CRC & timeout retry), and status indication for easy maintenance.
Wide Environmental Adaptability: Excellent resistance to vibration, shock, and temperature fluctuations for harsh industrial environments.
Global Certifications: Complies with UL, cUL, CE (EMC/RoHS), KC, and marine certifications (LR, NK, DNV, ABS), ensuring worldwide applicability.
