SIMATICS S7-300

Overview of S7-300 PLC
Modularized medium-sized PLC system to meet medium and small-scale control requirements
Modules with various performances can satisfy and adapt to the task of automatic control very well.
Simple and practical distributed structure and general network capability make the application very flexible.
The structure without fan design makes user's maintenance easier.
When the control task increases, it can be expanded freely.
A large number of integrated functions make it very powerful.
