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.

A configurable input channel, comprising:
- 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 selected type of 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.
A control system comprising:
- a plurality of configurable input channels for selectively receiving different analog sensor inputs, each configurable input channel comprising:
- 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 selected type of 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.
