Wiring Diagrams
Wire Your Controller 3-7
The following illustrations show the wiring diagrams for the MicroLogix 1200 controllers. Controllers with dc inputs can be wired as either sinking or
sourcing inputs. (Sinking and sourcing does not apply to ac inputs.) Refer to
Sinking and Sourcing Wiring Diagrams on page 3-12
The controller terminal block layouts are shown below. The shading on the labels indicates how the terminals are grouped. A detail of the groupings is shown in the table following the terminal block layouts.
TIP
This symbol denotes a protective earth ground terminal which provides a low impedance path between electrical circuits and earth for safety purposes and provides noise immunity improvement. This connection must be made for safety purposes on ac-powered controllers.
This symbol denotes a functional earth ground terminal which provides a low impedance path between electrical circuits and earth for non-safety purposes, such as noise immunity improvement.
