The source output operator’s panel connection unit (A16B–2202–0730,
or –0731) is connected to Series 15–B control units by the FANUC I/O
Link, and functions as the interface with the machine tool operator’s
panel.
Output from this connection unit is source–type. Input is sink–type
(24 V common). However, some connection units have DI that can be
switched to source–type input (0 V common).
Two connection units are available according to the number of I/Os.
