Specification

SEODescription

The QJ71PB92V is Mitsubishi Profibus Module designed as a Profibus-DP Master Module for seamless integration with MELSEC-Q series PLCs. It supports up to 32 Profibus-DP slave devices with a maximum data exchange capacity of 244 input/output bytes per slave, enabling efficient communication across industrial networks. The module operates at Profibus-DP speeds up to 12 Mbps and features a built-in RS-485 interface for direct connection to Profibus-enabled sensors, drives, and I/O modules. With an operating voltage range of 5VDC ±5% via the PLC backplane and a temperature tolerance of 0–55°C, it excels in harsh manufacturing environments such as automotive assembly, packaging lines, and process control systems. Key advantages include real-time diagnostics, flexible topology support, and compatibility with GX Configurator-DP software for simplified setup. However, its configuration requires specialized knowledge of Profibus protocols, and the module lacks native support for Profibus-PA devices without additional interfaces. The QJ71PB92V’s robust design ensures reliable data exchange in high-noise industrial applications while maintaining compliance with Profibus International standards.
