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.
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.
