The Mitsubishi NZ2EX2B1N-16D is a programmable controller remote I/O expansion module for MELSEC distributed automation architectures, catalogued under PLC expansion modules. As a slice-style expansion rather than a CPU or specialty card, it extends digital I/O density at the field end of a MELSEC rack — placed remote from the controller and addressed over the distributed-I/O link rather than the backplane.
None of the listed peers (QD70P4, FX2N-8EX-ES/UL, FX2N-16CCL-M) are true alternatives: QD70P4 is a positioning module in a different MELSEC family, and the FX2N pair uses the FX backplane rather than the MELSEC distributed-I/O link. Specifying the same order code against an RFQ is the cleanest path.
No — QD70P4 is a positioning module in a different MELSEC family, so it is not a pin-compatible swap for a distributed-I/O expansion slot.
