The interfacing of a GS-120 light curtain to a machine
can be achieved by means of an interface unit such as
the Pilz PNOZ 8. The circuit diagram for the PNOZ 8
and the typical connections to the GS-120 light curtain
and the machine are shown in Figure 39 below.

A number of manufacturers produce units containing
circuits of this type. Care should be taken to ensure that
the inputs of these units can accept the volt-free outputs
of the light curtain, and that the outputs of the light
curtain are wired with one channel "pull up" and one
channel "pull down" so as to maintain the failure mode
integrity.
