Analog quantity − A
The following figures depict the conversion of temperature to an analog value of DC
voltage, using a transducer.
Such analog value conversions can be voltage, current, temperature, speed, pressure, and
flow. For example, temperature may continuously change over time as shown in the
figure. Since the changing temperature cannot be directly fed to the PLC, it must be fed
to the PLC by converting to identical analog quantity of DC voltage －10 ~+10V or
current 4~20mA using a transducer.
