It's a drop-in module for extending an AS-Interface network along the busbar — no separate cabling back to the cabinet for each sensor or actuator within reach. ## What It Does on the Line This extender clips onto a 40 mm AS-i busbar, picking up both power and communication from the bus itself. The two inputs handle standard 24 V DC sensors; the single output switches a 24 V DC load — typically a small valve or indicator light. Because it's bus-powered, you save a home-run cable for every I/O point within the busbar's reach. Mounting is a snap-on onto the busbar profile inside a panel or junction box. ## Deployment Context Commonly found in material handling, packaging lines, and assembly stations where AS-Interface reduces point-to-point wiring. The 40 mm busbar system is standard for Siemens AS-i installations; this extender fits that footprint without adapters.","metaTitle":"Siemens 3RK1400-1KG01-0WB1 AS-i Busbar Extender, 2I/1O 24V D","metaDescription":"Siemens 3RK1400-1KG01-0WB1 AS-i busbar extender, 2 inputs / 1 output, 24 V DC, for 40 mm busbar system.
