Systems for monitoring or control can include reconfigurable input and output channels. Such reconfigurable channels can include as few as a single terminal and a ground pin, or such channels can include three or four terminal configuration such as for use in four-terminal resistance measurements. Channel reconfiguration can be accomplished such as using software-enabled or firmware-enabled control of channel hardware. Such channel hardware can include analog-to-digital and digital-to-analog conversion capability, including use of a digital-to-analog converter to provide field power or biasing. In an example, compensation can be provided to suppress a leakage current from flowing through a digital output to a load connected to the reconfigurable channel terminal, particularly when the digital output is disabled.

Leakage reduction for multi-function configurable circuit

The present disclosure provides a method and device for overvoltage protection. Specifically, the present disclosure provides an overvoltage protection device which provides a feedback loop for electronic components such as amplifiers and digital to analog converters which require feedback. The overvoltage protection device also includes overvoltage switches in both the signal and feedback channels, which may be opened by a fault detector in the event of an overvoltage. The device also includes an overvoltage feedback channel coupled between the signal and feedback channels, and which also includes a switch which may be closed in the event of an overvoltage event. As such, the overvoltage device provides a closed loop feedback channel during an overvoltage event.
