2. Estimates can be provided for coatings and other specifications that are not given in the datasheet. Ask your OMRON representative for details.
*1. Always connect an AC load to a long-life relay output. The output will not turn OFF if a DC load is connected because a triac is used for
switching the circuit. For details, check the conditions in Ratings.
*2. Auxiliary outputs are contact outputs that can be used to output alarms or results of logic operations.
