6 I/O Circuits

6.1 Input Circuit

• When an internal power supply is used for the I/O power
supply, the allocation to the 24 VDC internal power supply
of the DX100 is approximately 1.5A. If the total current
consumption of the I/O circuits including that of other I/O
boards (such as the JZNC-YIU01-E unit) exceeds 1.5A,
use an external power supply.
For connecting external power supply, refer to Section 6.3
"Connection Example" on page 6-4.
NOTE
• When an external power supply is used for the I/O power
supply and the total current consumption of the I/O circuits
exceeds 2A, use a 24 VDC external power supply.
However, do not use the 24 VDC power supply from CN10
and CN11 for the 24 VDC power supply used at the relay
output contact.
• The I/O circuits of the XOI02B board are exclusive-use for
24 VDC. Connecting a power supply other than 24 VDC
causes damages to the circuits and malfunction.
