(3) External power supply specifications
The power supply (24VDC, 5VDC) for the card-sized I/O card must be supplied from an external source.
Prepare a power supply (stabilized power supply) that satisfies the following conditions per card.
Voltage Ripple/noise
Current
24VDC 24VDC±5%
240mVp-p
1A
5VDC 5VDC±5%
50mVp-p
0.4A
The output current is the value when 60mA x 16 points are used. Prepare a power supply that satisfies the
total output current of the 24VDC output.
Refer to "Appendix 8. Precautions for Compliance to UL/c-UL Standards", as well.
