What sits on the BOM line
The Mitsubishi NZ2GF2B1-32D is a 32-point remote I/O module for distributed programmable logic controller systems, classified under PLC expansion modules.
Where it lands in the panel
The module hangs off the PLCs and Accessories category, sitting in the PLC expansion modules sub-line; in practice that means it drops into a distributed I/O ring or remote field station beside the CPU, not into the base rack as a local I/O card.
