Abstract
A method for determining an actuation delay time for an electromechanical relay includes capturing a current waveform of an energized coil, determining a time at which the actuation component begins to move by analyzing the captured current waveform, and calculating the actuation delay time for the relay based on the time at which the actuation component begins to move. A method for determining a state of a latching relay includes energizing the coil of the latching relay, capturing a current waveform of the energized coil, and determining the state of the relay by analyzing the captured current waveform.
