Wiring Your Controller 3-7
Wiring Diagrams
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 3-10
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.
