• The product can compatible with both NPN transistor and PNP transistor. However, mixing use of NPN/PNP is
impossible. Operate the product NPN transistor output and PNP transistor output.
• Do not short-circuit input common (IN COM.) and output common (OUT COM.). It might cause the trouble with the laser
marker.
• The applied voltage and input/output current to each terminal must not exceed each maximum value shown above.
Exceeding the maximum applied voltage and the maximum output current will cause the laser marker to malfunction.

• Respective outputs are photo-coupler outputs. The regulation for output ON is based on the ON status of photo-coupler.
• OUT COM. (Y2, X12, X15, X18) on the I/O terminal block and OUT COM. (No.37) on the I/O connector are the common
terminals connected internally.
• Connect the power supply to IN COM. and OUT COM.
