Abstract
Example devices and methods for compensating for monitoring a surge protection device are provided. In some embodiments, a device is configured to couple to a surge protection device. The device comprises a processor that is capable of sending a DC current signal. A serial data interface is electrically connected to the processor and includes at least one shift register. The device also comprises a multiplexer coupled to the serial data interface. The serial data interface is operable to direct the DC current through the multiplexer. The device also comprises an analog to digital converter (optionally embedded within the processor) that is operable to output a digital signal corresponding to a voltage induced by the DC current signal. Returned DC signals represent surge protection device's health and a multitude of other surge module information.
