 Connection of External Power Supply for I/O
At factory setting, the internal power supply for I/O is used. If the external power supply for I/O
is used, connect it with following procedure.
1. Remove the wire connected between CN12-1 to -3 and CN12-2 to -4 of the robot I/F
unit.
2. Connect +24V of the external power supply to CN12-1 and 0V to CN12-2 of the robot
I/F unit.
• The internal power supply of 24V of about 1A of NX100 can be used for I/O.
Use external 24V power supply for higher currents and to isolate the circuit inside and
outside the NX100.
• Power supply circuit for I/O (+24 VU, 024 VU) has 3A fuses (FU1, FU2).
• Install the external power supply outside the NX100 to avoid electric noise problems.
• If the internal power supply is selected and the external power supply is connected to
CN12-1 to -3 and CN12-2 to -4, do not connect the line of the external power supply to
the +24VU and 0VU terminals. The unit may malfunction if the external power supply is
also connected.
