Abstract
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.
