Wiring Your Controller

This chapter describes how to wire your controller and expansion I/O. Topics

include:

• wire requirements

• using surge suppressors

• grounding the controller

• wiring diagrams

• sinking and sourcing wiring diagrams

• controller I/O wiring

• wiring your analog channels

• expansion I/O wiring

Wiring Requirements

Wiring Recommendation

• Allow for at least 50 mm. (2 in.) between I/O wiring ducts or terminal

strips and the controller.

• Route incoming power to the controller by a path separate from the

device wiring. Where paths must cross, their intersection should be

perpendicular.

ATTENTION

Before you install and wire any device, disconnect

power to the controller system.

ATTENTION

Calculate the maximum possible current in each

power and common wire. Observe all electrical

codes dictating the maximum current allowable for

each wire size. Current above the maximum ratings

may cause wiring to overheat, which can cause

damage.

United States Only: If the controller is installed within

a potentially hazardous environment, all wiring must

comply with the requirements stated in the National

Electrical Code 501-10 (b).
