Section 2-2
Note (1)Under the worst conditions, the service life of output contacts is as shown
above. The service life of relays is as shown in the following diagram as a
guideline.
(2)With the CPM1A-16ER/CP1W-32ER/CP1W-16ER, the load current is
restricted depending on the ambient temperature. Design the system con-
sidering the load current based on the following graph.
(3)CP1W-32ER’s maximum number of simultaneously ON output points is 24
(75%). Design the system considering the simultaneously ON points and
load current based on the following curve.
