Distributed I/O in the control cabinet (IP20)
SIMATIC ET 200S
SIMATIC ET 200S is the multifunctional and bit-modular I/O system with IP20 degree of protection and can be
exactly tailored to the automation task. Thanks to its rugged design, it can also be used for increased mechanical
loads.
Design
A SIMATIC ET 200S station comprises up to 63 I/O modules. The I/O modules can be combined as required.
The SIMATIC ET 200S is configured with permanent wiring: All of the modules are plugged into purely mechanical
Terminal Modules. These Terminal Modules contain all the wiring and can be optionally mounted on 35
15 mm or
35
7.5 mm standard mounting rails.
This has the following advantages:
• Easy implementation of the wiring without additional electronic components
• Fast and safe wiring check even when energized
• Tool-free replacement of the electronic modules
• Automatic encoding of the electronic modules to ensure confusion-free replacement
Components
The SIMATIC ET 200S distributed I/O system consists of the following components:
• IM 151, IM 151-3 PN Interface Module
• Digital and analog electronic modules
• Technology modules, e.g. for counting and position detection tasks
• Motor starter and frequency converter
• Terminating module (included in scope of delivery of IM 151)
• Power Modules
SIMATIC ET 200S Compact
• Expandable block I/O with IP20 degree of protection with 32 channels onboard, consisting of terminal block and
electronic block
Configuration and parameter assignment
The ET 200S is configured and parameterized via STEP 7 or via the TIA Portal.
