What the line carries
The NZ2GFSS2-16DTE: Its listed lifecycle stage is current, so the line is still being carried against active BOMs rather than routed through last-time-buy or surplus channels.
Selection and panel-side notes
Control units in this class sit on the panel as discrete logic blocks; the 24VDC supply on the NZ2GFSS2-16DTE matches the standard backplane rail commonly used with this Mitsubishi line, so wiring is to the conventional DC power terminal rather than a dedicated field supply.
