Two ECOFAST RS485 connections bring the bus in and out, and the ID connector lets you set the station address without opening the controller cabinet. It's the field-serviceable link: swap it with the rail powered down and you're back online without a full node swap. ## Physical fit and thermal load Width 79 mm, Height 60 mm, Depth 30 mm. Power loss typ. 2 W, dependent on loop current.","metaTitle":"Siemens 6ES7194-3AA00-0AA0 SIMATIC DP ECOFAST Block, 2x RS48","metaDescription":"Active production SIMATIC DP connection block for ET 200ECO. 2x ECOFAST RS485 connections, ID connector, address setting.
