Product Description

The QJ71MB91 module is a dedicated MELSEC-Q Modbus communication interface designed for seamless integration in industrial automation systems. This module supports Modbus RTU/ASCII protocols, enabling reliable data exchange between PLCs and peripheral devices via RS-485 or RS-232 interfaces. It accommodates up to 64 Modbus slave devices simultaneously, offering configurable data mapping for 32 input and 32 output registers. Operating within a 24VDC ±10% power range and -10°C to 55°C temperature limits, the QJ71MB91 communication module excels in harsh environments across manufacturing, energy management, and water treatment industries. Key advantages include real-time protocol conversion, error diagnostics, and compatibility with legacy Modbus systems, though it requires specific GX Works2 configuration expertise. The compact 98mm x 27.4mm x 90mm form factor ensures easy DIN rail mounting without additional power requirements. Its robust construction and protocol flexibility make it ideal for SCADA integration, HVAC controls, and process monitoring applications where standardized industrial communication is critical.
