an input circuit that uses and
analog-to-digital converter to translate a continuous analog signal, measured
by an analog device, into a digital value that can be used by the processor.
Analog input interface –
an output circuit that uses a
digital to analog converter to translate a digital value, said from the
processor, into an analog signal that can control a connected analog device
Analog output interface –
a continuous signal that changes smoothly
over a given range, rather than switching suddenly between certain levels as
discrete signals do.
Analog signal –
a device that
translates analog signals from field devices into binary numbers that can be read by the processor.
Analog-to-digital converter –
a designated path for signal.
a signal transmission system
where inputs and outputs have individual return lines for each channel, as
opposed to all data running through one line.
Differential input/output –
a device that translates
binary numbers from a processor into analog signals that field devices can
Digital-to-analog converter –
the smallest detectable increment of
changing analog output data to reflect engineering
an analog I/O connection in
which the commons are electrically tied together resulting in only one return
Single ended input/output –
a device used to convert physical parameters,
such as temperature, pressure, and weight into electrical signals.
a device that amplifies a voltage signal.
