The Mitsubishi RJ71EN71 is an Ethernet network module in the MELSEC iQ-R PLC expansion family, designed to slot into the iQ-R backplane alongside the CPU and other slices to extend network connectivity on the rack. It is cataloged as a PLC Expansion Module under the PLCs and Accessories family, meaning it is sourced as a BOM line against a specific slot assignment rather than as a standalone field device.

Frequently asked questions
What is RJ71EN71's listed weight on this component line?
0.45 kgs, consistent with a standard single-slot iQ-R network slice.
Will RJ71EN71 drop into a panel that was specified around AJ65BT-D62 without rewiring?
No — the two parts serve different functions (Ethernet network module versus CC-Link remote I/O module), so a swap into an existing AJ65BT-D62 slot would require re-engineering the rack, the fieldbus map and the CPU configuration, not just a physical card swap.
