Block I/O in IP67 degree of protection with PROFINET connection

The SIMATIC ET 200eco PN is a compact block IO with PROFINET connection in IP 65/67 degree of protection for cabinet-free installation directly on the machine. Thanks to its fully-sealed zinc die-cast housing, the ET 200eco PN is mechanically very rugged and resistant to vibrations, dust, oil, or humidity.
The SIMATIC ET 200eco PN can be flexibly expanded via PROFINET and supports both star and line topologies within a system. 
Furthermore, it enables users to profit from an integrated diagnostics concept and from the high performance of PROFINET.
In addition an I/O Link master module is available.
ET 200eco PN is the seamless supplement for applications with a high degree of protection in addition to the modular ET 200pro I/O family.

NEW - Product Announcement: Failsafe Digital In-/Output Module - NEW

F-DI 8 x 24 VDC, 4xM12 / F-DQ 3 x 24 VDC/2.0A PM, 3xM12
Compact, very robust, encapsulated  PROFINET periphery as block IO for processing of failsafe digital signals in IP65/67 degree of protection for mounting outside the cabinet and contacting with M12 interface technology.
It allows up to 8 (up to PL d/ SIL 2) resp. 4 (up to PL e/SIL 3) sensors in and three actors (up to PL e/ SIL 3) out to be connected.  Actors are always connected or disconnected on two channels (plus/minus –switched).

Area of application

With a high degree of protection, ruggedness and small dimensions, ET 200eco PN is especially well suited for use at machine level, especially in the machine building and automotive industry.


  • Especially rugged design

  • Small footprint

  • Comprehensive range of modules

  • Easy installation and setup

  • Channel by channel diagnostics

  • Integrated  2-port switch

Design and function

The SIMATIC ET 200eco PN is available both with 8 and 16 digital inputs or outputs in 2 different design sizes. The individual inputs and outputs and the power and bus are connected by means of an M12 connection system. The sensors and actuators, as well as power and bus are connected via the rugged M12 connection system. The ET 200eco PN is available with two different enclosure designs:

  • Modules with 4 x M12 connection in a long and narrow design (30 x 200 x 37 mm)

  • Modules with 8 x M12 connection in a short and wide design (60 x 175 x 37 mm)

The modules can be mounted head-on or rotated 90 degrees to the side. The PROFINET connection with a 2-port switch is integrated into every module. With its fully-sealed zinc die-cast housing, the
ET 200eco PN allows operation at an ambient temperature range from -40 °C to 60 °C and a vibration strength of 20 g.
