Mitsubishi QJ71C24N is a MELSEC-Q series serial communication module used in PLC network integration, machine control systems, industrial communication cabinets, and factory automation projects. It is designed to connect Q series PLC systems with external devices through serial communication, making it suitable for data exchange between PLCs, HMIs, barcode readers, temperature controllers, meters, inverters, and other industrial equipment.
This model is a valuable communication spare part for existing MELSEC-Q systems. In many production lines, communication module failure can interrupt machine data exchange, device monitoring, parameter transmission, or operator interface communication. QJ71C24N is often searched by maintenance engineers and spare parts buyers when a Q series communication module needs replacement or system repair.

QJ71C24N is used in MELSEC-Q PLC systems together with Q series CPU modules, base units, power supply modules, I/O modules, HMI panels, measuring instruments, barcode readers, controllers, and industrial communication devices. It is suitable for packaging machines, production lines, process equipment, utility systems, data collection panels, and factory automation networks.
When replacing QJ71C24N, confirm the complete model number, communication port type, wiring method, protocol setting, baud rate, station configuration, PLC program, and existing system parameters. Communication faults may also be caused by cable damage, wrong parameter settings, external device failure, protocol mismatch, or grounding problems, so the complete communication loop should be checked before replacement.
Related models include QJ71C24N, QJ71C24N-R2, QJ71C24N-R4, QJ71E71-100, QJ71LP21-25, QJ71BR11, and QJ71DN91. These modules may differ by communication interface, network type, protocol support, wiring method, and system application.
DF Automatic supplies Mitsubishi MELSEC-Q communication modules, CPU modules, digital I/O modules, analog modules, power supplies, base units, HMI panels, servo systems, inverter drives, and industrial automation spare parts for factory maintenance, equipment repair, and PLC system replacement.
