What it is
The Mitsubishi NZ2GF2B1N1-16D is a 16-point programmable controller remote I/O module built for distributed automation systems, sitting in the PLC expansion slot family as a slice module that mounts separately from the controller CPU.
What it does in the panel
As a remote I/O slice, the module fans sixteen field-side signals out over the network to the controlling CPU rather than back to a backplane in the main panel — so the cabinet can stay small while the I/O lives near the sensors and valves it serves.
Lifecycle and sourcing posture
Lifecycle stage is recorded as current, so the BOM line is not on a last-time-buy clock and the part is specified into new builds against an RFQ rather than pulled from surplus.
