z Output Specifications for Relay Outputs
(CP1W-8ER/16ER/20EDR1/32ER/40EDR)
• Estimating the Service Life of Relays
The service life of output contacts is as shown in the following diagram.
• Restrictions of CP1W-16ER/32ER
In addition to the above restrictions, limit the output load current so that it satisfies the following derat-
ing curve.
