Product Description

The Mitsubishi MELSEC-Q QJ71LP21GE is a Profibus-DP communication module designed for industrial automation systems. This MELSEC-Q LP21GE Controller integrates seamlessly into the MELSEC-Q series, functioning as a Profibus-DP master/slave with support for up to 124 connected nodes via RS-485 interfaces. It operates at 12 Mbps communication speed and requires a 24V DC power supply (10.2–26.4V range) within a temperature tolerance of 0–55°C. Ideal for automotive, chemical, and machinery sectors, the QJ71LP21GE excels in real-time data exchange and supports cyclic/acyclic messaging for distributed I/O systems. Key advantages include high noise immunity, configurable diagnostics, and compatibility with Profibus-DPV0/V1 protocols. While it lacks onboard I/O points or display, its compact design enables seamless integration with MELSEC-Q CPUs. The module requires GX Configurator-DP software for setup and does not incorporate battery or screen components.
