Note 1. The service life of relay output contacts shown in the table assumes the
worst conditions. The following graph shows the results of OMRON's ser-
vice life tests at a switching rate of 1,800 times/hour.
2. The CPM1A-20EDR Expansion I/O Unit with Relay Outputs does not con-
form to the EC Directives. Use the CPM1A-20EDR1 or CPM1A-8ER Expan-
sion I/O Unit, which has the CE marking, when conformance to EC Direc-
tives is required.
