⿎ Operation of output signal on I/O terminal block
Reference
• The ON/OFF listed in this section refers to the ON/OFF operations. It does not refer to the voltage level (High/Low).
Terminal
Name/Description
No.
B1
0V OUT: Internal power supply 0V
Use this terminal as the power supply for the I/O signals when operating laser marker without external
power supply.
This terminal can be also used as the power supply for external devices such as a sensor or an encoder.
Notice
• Make sure to use +12V OUT (A1) for the internal power supply with this 0V OUT (B1). Do not mix the connecting pattern
for using external and internal power supply.
• Do not connect anything to this when using the external power supply for I/O control.
• When using the internal power supply (A1, B1), the total current of the power supply for the external device and the
consumption current for the I/O control should be less than 300mA.
B2
• For NPN models *1
OUT COM.: Output common
The common terminal for each output of the I/O terminal and I/O connector. This B2, A11, B11 and No. 37
of I/O connector are the common terminals connected internally.
For NPN models, this terminal is connected to the "- (minus)" side of power which is used for control.
• For PNP models ("-C" in the end of the model name) *1
IN COM.: Input common
The common terminal for each input of the I/O terminal and I/O connector. This B2 and No. 37 of I/O
connector are the common terminals connected internally.
For PNP models, this terminal is connected to the "- (minus)" side of power which is used for control.
Notice
• Do not invert the power wiring of I/O terminal and I/O connector. It may cause a failure. When this terminal is connected
to the power supply, it is not necessary to supply the power to the other IN COM. or OUT COM. on I/O connector.
• At the factory shipments, IN COM. and OUT COM. of I/O terminals are connected to the power supply terminals by
short bars respectively. When using the external power supply or connecting to any external devices, remove the short
bars from the terminals to be used.
• Short-circuiting IN COM. and OUT COM. in supplying power might cause the short out and also cause the failure with
the laser marker. Be sure to check the wiring before starting the laser marker.
Reference
• Connect IN COM. and OUT COM. to the power supply respectively.
NPN type of laser marker:
PNP type of laser marker:
• For the connecting details, refer to "2-3 Connecting I/O Terminal Block" (P.42).
B3
REMOTE OUT: Remote mode output
This output turns ON while the laser marker is in the remote mode.
Make sure that this terminal is turned ON and start the external control by I/O or serial communication
commands.
