Estimating the Service Life of Relays
Under normal 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.

Relationship between Continuous Simultaneous ON Rate and Ambient
Temperature
There are restrictions on the power supply voltage and output load current imposed by the ambient
temperature. Make sure that the power supply voltage and output load current are within the follow-
ing ranges.
Note The above restrictions apply to the relay output load current from the CPU Unit even if Expansion I/O Units
are not connected.
