Overview of I/O Moduls
I/O modules are the interface between the SIMATIC S7-1500 and the process:
- Digital and analog modules provide exactly the inputs/outputs required for each task.
- Technology modules for SIMATIC S7-1500 and ET 200MP
- With integrated functions for high-speed counting and position detection
- With integrated inputs and outputs for tasks at the process level, and short response times
- Communication modules for SIMATIC S7-1500 and ET 200MP
- For data exchange using point-to-point coupling
- For connecting to PROFIBUS
- For connecting to Industrial Ethernet
- Connection system for user-friendly, low-overhead wiring of the S7-1500 and ET 200MP modules
Application of S7-1500 SM 521
Digital input modules record 24 V DC or 230 V AC signals in the plant and forward them to the control. Switches and 2, 3 or 4-wire proximity switches can be connected.
35 mm wide input modules have settable parameters and diagnostic functions and can thus be adapted flexibly to the respective process requirements.
Low cost 25 mm wide input modules do not have settable parameters or diagnostic functions and are therefore very easy to integrate into the engineering. They are recommended for use in locations where only very few input channels are necessary or under conditions of use in which a high number of channels must be implemented in a very limited space.
Both module types can be used side by side in one station as required. Uniform features and shared system accessories guarantee easy handling.
