Siemens S7-300 PLC Digital I/O Module

Model: 6ES7323-1BL00-0AA0

Digital input/output modules possess digital inputs/outputs for the automation system. Digital sensors and actuators can be connected via these modules.

Use of the digital input modules offers the following advantages for users:

Optimum adaptation;
the number of inputs/outputs can be adapted to the respective task using optional combination of modules. Superfluous investments no longer exist

Flexible process connection;
the automation system can be connected to the process using many different digital actuators and sensor

Digital modules may have different properties. You can program the properties of certain modules. All information in this chapter applies only to programmable digital modules:
