The following two wirings are available since non-polar PhotoMOS relay is used for output
circuit.
 Be sure to wire the output circuit properly because it has no protection circuitry
for short-circuit and reverse-connection. Improper wiring may cause malfunction
of the parts on the board and then improper function of the robot system.
 To comply with European Machinery Directive, use plus common (PNP) to
prevent the load from unintended operation in the event of a ground fault in the
wiring between the controller and the load.
