QJ71E71-B2
The Mitsubishi QJ71E71-B2 Ethernet Module integrates with Q Series PLC systems, enabling reliable high-speed communication via Mitsubishi E71 interface for seamless industrial network connectivity and data exchange.

Product Description

The Mitsubishi Q Series PLC Module QJ71E71-B2 Ethernet Module is designed for robust industrial communication, integrating the Mitsubishi E71 Communication Interface to enable seamless data exchange in automation systems. This module supports 10BASE-T and 10BASE5 Ethernet standards, featuring a 24 V DC operating voltage range (20.4–28.8 V) and an operational temperature range of 0–55°C. It provides direct connectivity to Q Series PLCs, facilitating real-time control and monitoring in manufacturing, automotive, and process industries. Notable advantages include high-speed data transfer (10 Mbps), reliable TCP/IP and UDP protocol support, and compatibility with Mitsubishi's MELSEC network architecture. However, it lacks support for modern high-speed Ethernet standards like 100BASE-TX. The module does not include a built-in battery or display, focusing solely on industrial-grade communication stability. Its compact design ensures easy integration into control panels, with DIN rail mounting for efficient space utilization. Ideal for legacy system upgrades, this module enhances data visibility while maintaining backward compatibility with Mitsubishi's industrial ecosystems.
