Specifications for External Power Supply Expansion
Appendix H
•
10-point, 14-point and 20-point AC-power-supply CPU Units (Model CP1L-L
DR-A)
The external power supply for 10-point AC-power-supply CPU Units (Model CP1L-L
DR-A) as well as
14-point and 20-point power-supply CPU Units manufactured since May 2008 (Model CP1L-L
DR-A)
can be used beyond 200mA within the capacity range of the power supply built in the CPU Units.
Please calculate the usable capacity of external power supply according to the following example.
