Distributed I/O for use in the field

Made-to-measure distributed automation systems

Extending the I/O system beyond the control cabinet

The small, rugged SIMATIC ET 200 systems with a high IP65/67 degree of protection can be used in harsh industrial environments and directly at the machine. They are ideally suited for the rapid and flexible set-up of distributed automation solutions. SIMATIC ET 200 systems for use outside of control cabinets are shock, dirt, and water-resistant and available in a range of versions, from a compact block I/O to a multifunctional modular system. You save on supplementary components and space, reduce your cabling requirements, and benefit from extremely short response times.

The right solution for indoor environments beyond the control cabinet

In operating and protecting your control system outside of the control cabinet, there are a number of solutions available through Distributed I/O blocks. The ET200pro is a modular and multifunctional device with, and integrated safety technology. By installing an ET200pro directly onto a machine without a control cabinet saves plenty of space, and its flexible connection options via IO-Link allow the device to connect to devices in the control cabinet, and outdoors.

The ET200AL is a lightweight and mobile module with unlimited flexibility when mounting for hard-to-reach parts. Siemens’ compact device is very easy to install, wire and commission, and in the event of a fault, its failsafe shutdown will protect consumers. The ET 200iSP is an intrinsically-safe solution for use in dusty and gaseous atmospheres at ambient temperatures from -20 to +70 °C and is fully modular.


Durable block I/O for outdoor environments

When setting up an outdoor control system, the ET200eco provides a PROFIBUS solution, and the ET200eco PN provides a PROFINET solution. While compact in size, both modules are rugged and well-protected by their metal housing, making them reliable in any weather and environmental condition, including explosion hazard areas.


Communication with the entire control system

All ET 200 products for use in the field and the control cabinet can communicate with each other, and operate separately without interruption.
