Delta AS Series User Manual

4.8.2.2 Relay Output Circuit
Relay terminals have no polarity. They can be used with alternating current that passes through a load, or with
direct current that passes through a load. The maximum current that can pass through every relay terminal is 2
A, and refer to each product specification for the maximum current that can pass through every common
terminal. Life cycle curve: The lifetime of a relay terminal varies with the working voltage, the load type (the
power factor cosψ, the time constant t(L/R)), and the current passing through the terminal. The relation is
shown in the life cycle curve below.
