How It Relates to the LJ71E71-100
The LJ71E71-100 is a functional peer in the PLC expansion category but belongs to Mitsubishi’s L-series—different backplane architecture. The QJ71FL71-T-F01 plugs into a MELSEC-Q rack; the LJ71E71-100 mates with an L-series base. No direct drop-in without replacing the bus carrier.
