4-2-3 Input rating and input circuit
This section shows the input rating and the input circuit for the I/O terminal block input and the I/O connector input. Note
that the input rating and circuit of the interlock connector are different from those shown here. Refer to “4-4-2 Input and
output circuit of interlock” (P.106).

• This product supports both the NPN transistor output and the PNP transistor output. However, the wiring from I/O
terminal block and the I/O connector respectively cannot be used as NPN/PNP mixed. Operate the product after
selecting either NPN or PNP.
• Do not short-circuit 24V (X1, Y3) and 0V (Y1, X3). Also, do not short-circuit IN COM. (X2) and OUT COM. (Y2, X12, X15,
X18). Starting the laser welding machine with these terminals short-circuited will cause the laser welding machine to
malfunction.

• Respective inputs are bidirectional photo-coupler inputs. The regulation for input ON is based on the ON status of photo-
coupler.
• IN COM. (X2) on the I/O terminal block and IN COM. (No.1) on the I/O connector are the common terminals connected
internally.
• Connect the power supply to IN COM. and OUT COM.
• Wiring LASER STOP 1/LASER STOP 2 terminals by non-voltage contact (dry contact) is recommended.
• DC 2-wire sensor cannot be connected to any input.
