Note Not all combinations of function 1 and function 2 specifications are possible
for Option Units (E53-@@@@).
*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.
