Specification

SEODescription

The QJ71GP21-SX communication module, part of the MELSEC-Q GP21-SX series, is a CC-Link IE Field Network module designed for high-speed industrial networking. It supports seamless integration with up to 120 stations via its gigabit Ethernet-based CC-Link IE Field Network interface, enabling real-time communication at 1 Gbps. Operating within a 24 VDC ±10% voltage range and a temperature tolerance of 0–55°C, this module is ideal for automation, manufacturing, and process control industries. Its key advantages include robust data synchronization, reduced cabling complexity, and compatibility with Mitsubishi’s PLC systems. However, it requires specialized configuration tools and expertise, and its reliance on proprietary protocols may limit interoperability with non-Mitsubishi devices. The module excels in environments demanding high-speed, low-latency communication.
