Relay coil (AC)

The relay coil is energized when actuated with alternating current. The relay coil can also be actuated with direct current. In this case though, it must be noted that a higher actuating current flows through the coil due to the lack of reactance.

The relay coil is modeled as a series connection of an ideal resistor and an ideal coil. The resistance and inductance are automatically calculated from the component parameters.
