Output Rating And Output Circuit - Panasonic LP-RF Series Setup & Maintenance Manual

4-4-2 Output rating and output circuit

This section shows the output rating and the output circuit for the I/O terminal block output and the I/O connector output.
Note that the output rating and circuit of INTERLOCK MONITOR terminals (Y16, Y17, Y18, Y19) are different from those
shown here. Refer to"4-4-3 Interlock terminal rating and I/O circuit" (P.100).

• 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. 1 (X2) and OUT COM.1 (Y2, X12).
Starting the laser marker with these terminals short-circuited will cause the laser marker to malfunction.
• 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.
• IN COM. 1, OUT COM. 1 of the I/O terminal block and IN COM. 2, OUT COM. 2 of the I/O connector are independent.
If you use the I/O connector terminal, connect input common/output common of the I/O terminal block and the I/O
connector to power supply respectively.
