Distributed I/O without control cabinet (IP65/IP67)
SIMATIC ET 200eco
SIMATIC ET 200eco is a distributed I/O device with IP65/67 degree of protection.
• Simple handling and installation
• Cost-effective processing of digital signals (also fail-safe) on the PROFIBUS DP
• Can be used at the machine level due to high degree of protection and ruggedness
• PROFIBUS DP interface connection via M12 or via standardized hybrid fieldbus connection (ECOFAST) thanks
to flexible connection blocks
The compact ET 200eco block I/O is an ideal addition to the modular ET 200pro I/O family for applications in a
high degree of protection.
Design
ET 200eco consists of a basic module and connection block.
A compact, coordinated range of modules for digital I/Os is available for applications and integration of
PROFIBUS applications.
The PROFIBUS DP can be connected via the variable and flexible connection blocks, depending on the
customer's wishes, via 2
M12, 2
7/8" or 2
hybrid fieldbus interface connection (ECOFAST).
The T functionality for PROFIBUS DP and the power supply are already integrated in the connection block so that
plants can now be handled without interruption and without the use of additional components during
commissioning and servicing of bus cables.
The pin assignment for the actuators and sensors is adapted to the IP65/67 standardization trend.
Depending on the connection block, the setting of the PROFIBUS address is either visible or can be connected.
With ECOFAST interfaces, the proven identification connector is used; with M12, 7/8" interfaces, two externally
visible rotary coding switches are used to set the PROFIBUS address.
The connection block can be removed from the basic module and screwed on again under power, so that
PROFIBUS and power supply remain permanently active in the application.
Components
Various modules are available for the applications:
8 DI, 16 DI, 8 DI/8 DO (1.3 A), 8 DI/8 DO (2 A), 8 DO (2 A),16 DO (0.5 A) and 4/8 F-DI
Configuration and parameter assignment
The ET 200eco is configured and parameterized via STEP 7 or the TIA Portal.
