3.4 Cautions Related to Parallel Input/Output
The input/output ports are housed in the particular controller being used. The ports differ
according to the inspection specifications. See the individual controller’s user manual
for details.
3.4.1 About Parallel Output
− Depending on the controller being used, the output is either NPN open collector,or
Photo − MOS. Be certain to use them within their rated load current range.
− The Photo − MOS output can be used as either PNP output or NPN output, but when
connecting, make them uniform for the controller.
− The controller has only a low capacity to carry current. It takes into consideration
connections with a PLC, etc., as shown above. Do not connect to a heavy load such
as a directly − connected bulb. When such a requirement exists, pass it through our
Power − Photo relay.
− The output load should be within the range specified below (Maximum 24mA per 1
Signal).

− The output circuit contains no internal fuse. When it is necessary to prevent output
circuit burnout in the event of an output load short circuit, attach an external fuse.
However, there are cases when internal elements cannot be protected in the event
of a short circuit.
− The common flash line has a specialized terminal. Do not use it together with other
common lines.
