Application 1 : Standard Mode

Introduction
Below are the wiring scheme and the parameter assignment of SM 326; DI 24 x DC 24V for
application 1: Standard mode
Diagnostic messages, possible causes of the problem and their corrective measures are
found in tables in the chapter "Diagnostic messages of SM 326; DI 24 x DC 24V (Page 99)".
Wiring diagram of application 1 with single-channel connection of a one sensor
A sensor is wired to a single channel for each process signal. The sensors can also be
connected to an external sensor supply.
