4.1 4.1 Overview
Introduction
This chapter contains a description of the basic procedure for connecting signal transducers
to analog inputs and analog outputs and points to which particular attention must be paid.
The figures below do not show the connecting lines required to connect the electrical
potentials of the analog input module and transducers.
Always adhere to the general information on connecting transducers.
You will find special connection options described for the corresponding module.
Installation and wiring
You will find information about installation and wiring in Operating Instructions S7-300, CPU
31xC, and CPU 31x: Installation Online at:
