Distributed I/O without control cabinet (IP65/IP67)
SIMATIC ET 200eco PN
The compact block I/O SIMATIC ET 200eco PN is a distributed I/O device with degree of protection IP65/66/67
with easy handling and installation. With ET 200eco PN, digital, analog and IO-Link signals can be processed on
PROFINET. With a high degree of protection, ruggedness and small dimensions, the ET 200eco PN is especially
well-suited for use at the machine level. The ET 200eco PN is an ideal supplement in addition to the modular
ET 200pro I/O family for applications with a high degree of protection.
Design
• Compact module with M12 connection technology
• Coordinated range of modules for I/Os for the use and integration of PROFINET applications
• Two load voltage supplies (4 A each) which are used by the compact module and can be looped through to an
additional compact module (line topology)
• Alternative connection of load voltage supplies via additional terminal block with higher current carrying capacity
(10 A each) and looping through via ET 200eco PN
• Splitting of the supplied load voltage supplies into 4 lines by means of a voltage distributor – the distributed load
voltages are electronically protected against short-circuits
• PROFINET connection via an M12 connector and looping through to an additional PROFINET device as needed
Components
Various compact modules are available for the applications:
8 DI, 16 DI, 8 DO, 16 DO, 8 DI/DO, 8 AI, 4 AO and IO-Link master. The modules are also available in various
designs (e.g. with regard to maximum output current).
IO-Link:
The IO-Link master module 4 IO-L + 8 DI + 4 DO allows the easy integration of IO-Link sensors and
actuators from various manufacturers into PROFINET.
Up to 4 IO-Link devices (3-wire connection) can be connected to each IO-Link master module. In addition, up to
8 standard sensors and 4 standard actuators can be connected.
Configuration and parameter assignment
The ET 200eco PN is configured and parameterized via STEP 7 or the TIA Portal.
