It handles the distribution function for AS-i flat cables, so the bus power and data run straight through the board to the drop points. Rated for 7 A per contact, it can feed a cluster of small actuators or sensors off one tap without overloading the piercing contacts. ## Mounting and environmental range Ambient temperature range from -25 °C to +85 °C covers unheated outdoor enclosures and hot machine-side locations.","metaTitle":"Siemens 3RK1901-1NN00 AS-Interface Distributor, IP67, 7A","metaDescription":"Siemens 3RK1901-1NN00 AS-Interface standard distributor for flat cable.
