Claim:
1. A monitoring and protection system comprising: a plurality of input/output (I/O) channels communicatively coupled to at least one sensor sensing machinery operations; an analog-to-digital converter (ADC) communicatively coupled to the plurality of I/O channels, wherein the ADC is configured to receive at least one signal from the plurality of I/O channels communicated by the at least one sensor and is configured to convert the at least one signal to a digital data; a processor communicatively coupled to the ADC, wherein the processor is configured to derive a state based on the digital data; and an excitation system included as a component of the ADC, wherein the excitation system is configured to excite an excitation signal for a selected system state as a replacement for the at least one signal; and a first component, wherein the first component is configured to process the excitation signal in lieu of the replaced at least one sensor signal transmitted via the at least one sensor.
