QJ72LP25GE Mitsubishi Universal Model Redundant Power Supply Module 5 V DC/3 A

QJ72LP25GE Description

The QJ72LP25GE is a high‑speed optical loop network module designed for remote I/O communication in industrial control systems. Operating as a remote station in a duplex fiber‑optic ring, it enables reliable, noise‑immune data exchange between controllers and distributed I/O devices at 10 Mbps transmission speed. Using GI‑62.5/125 multimode fiber, it supports network distances up to 30 km and up to 65 stations (1 master + 64 remote I/O stations), making it ideal for large‑scale, EMI‑prone industrial environments.

 

QJ72LP25GE Key Features

• Duplex Optical Loop Topology: Dual‑ring redundancy ensures uninterrupted communication if a cable fault occurs.
• High Noise Immunity: Fiber‑optic transmission eliminates EMI/RFI interference for stable operation in harsh electrical environments.
• Large Network Capacity: Supports up to 65 stations and 16,384 link points (LB/LW) for extensive I/O control.
• Long‑Distance Communication: Maximum 30 km total network length; up to 2 km between individual stations.
• High‑Speed Data Transfer: 10 Mbps baud rate for fast, real‑time data exchange.
• RAS Diagnostic Functions: Built‑in loopback, cable break detection, and line monitoring for easy maintenance.
• Compact Form Factor: Single‑slot installation with low power consumption for space‑saving integration.
• Multi‑Protocol Compatibility: Supports MELSECNET/H and MELSECNET/10 modes for flexible system integration.
