7.3 I/O Contactor Unit
7-17
• The internal power supply of 24V of about 1A of XRC can be used for I/O.
Use external 24V power supply for higher currents and to isolate the circuit inside and
outside the XRC.
• The I/O power supply (+24 VU, 024 VU) has 3A fuses (FU3,FU4).
• Install the external power supply outside the XRC to avoid electric noise problems.
• When the internal power supply is selected, 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.
