2.1 Outline
The MC43 Controller continuously detects the
difference between a process measurement and its
set point, and produces an output air signal that is
a function of this difference and the type of control.
The output signal is transmitted to a control valve or
other control device. The process measurement,
set point, and output signal are indicated on the
controller.
