Specification

SEODescription

The RJ71EN71 Industrial Communication module, a key component of the MELSEC iQ-R Ethernet Module series by Mitsubishi, enables seamless integration in industrial networks. Designed as a Mitsubishi PLC Network Module, it features dual 10/100BASE-T ports for high-speed data exchange, supporting Ethernet/IP, Modbus TCP, and SLMP protocols. Compatible with up to 64 devices, it directly interfaces with MELSEC iQ-R series modules via a PLC base unit. Operating at 24 VDC (±10%) within 0–55°C, it excels in harsh environments across automotive, manufacturing, and energy sectors. Its advantages include real-time diagnostics, secure communication, and easy configuration via GX Works3; however, it requires expertise for advanced network optimization and lacks built-in Wi-Fi connectivity. Ideal for scalable, reliable industrial automation solutions.
