ABSTRACT:
Embodiments of the invention relate generally to a configurable analog input channel with galvanic isolation. In one embodiment, the invention provides a configurable input channel for selectively receiving one of a plurality of different analog sensor inputs. The input channel includes an interface for implementing switch settings for a selected type of input signal; a set of input terminals, wherein at least two of the set of input terminals are selectively utilized to correspond with the selected type of input signal; an analog-to-digital converter for converting the input signal into a digital output, wherein an operation of the analog-to-digital converter is determined based on the switch settings; and an isolation barrier for isolating the configurable input channel.
