 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 CN303-1 to -3 and CN303-2 to -4
of the universal I/O circuit board.
2. Connect +24V of the external power supply to CN303-1 and 0V to
CN303-2 of the robot I/O unit.
For the connection of the CN303 connector, refer to chapter 14.12
“WAGO Connector” at page 14-47.

In case of using external power supply
(Ready by Customer)
• The internal power supply of 24V of about 1.5A of DX200
can be used for I/O.
Use external 24V power supply for higher currents and to
isolate the circuit inside and outside the DX200.
• Power supply circuit for I/O (+24 VU, 024 VU) has 3.15A
fuses (F1, F2).
• Install the external power supply outside the DX200 to
avoid electric noise problems.
• If the internal power supply is selected and the external
power supply is connected to CN303-1 to -3 and CN303-2
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.
