Fieldbus connection block for ET 200ECO
The Siemens 6ES7194-3AA00-0BA0 is a SIMATIC DP connection block for the ET 200ECO distributed I/O family, routing two M12 and two 7/8" connectors and providing two rotary coding switches for PROFIBUS DP address setting. Typical power loss is 2 W, but that figure depends on the current looped through the block; factor it into your thermal budget if the connectors carry near-rated loads. Lifecycle stage is current.
