In general Marshalling box is a common Junction box where
all local sensor are terminated and a common cable taken to
remote monitoring station either Substation relay console
panel [RCP] or DCS or PLC.
On the other hand in PLC /DCS also use this word, where the
different I/Os wired to terminals and from there the cables
is drawn to field sensors/equipements/instrumens.
