Notice
• This product has NPN type and PNP type depending on the laser marker models. Make sure the model name and
connect correctly. (PNP type has “-C” in the end of the laser marker model name.)
• Do not short-circuit input common (IN COM.) and output common (OUT COM). It might cause the failure of the laser
marker.
Reference
• Respective outputs are photo-coupler outputs. The regulation for output ON is based on the ON status of photo-coupler.
• OUT COM. terminals on the I/O terminal block and on the I/O connector are the common terminals connected internally.
• Connect the power supply to IN COM. and OUT COM. by using either I/O terminal block or I/O connector.
