Preassembled Power Cable Interface for ET 200X
The Siemens 3RK1911-0CR40 is an ECOFAST power cable interface for the ET 200X distributed I/O family, preassembled with a HAN Q8 connector on both the sensor/actuator side and the control side (ST/BU). The cable uses 5 x 4 sqmm conductors and is available in any length greater than 3 m and less than 5 m, ordered in a minimum grid of 10 cm — meaning you specify the exact length in 10 cm increments within that band.
Integration Notes for the Controls Integrator
This cable mates directly to the ECOFAST power bus on an ET 200X station — no field wiring of the power connector is needed, which saves panel-build time and eliminates a common point of intermittent contact on high-vibration lines. The HAN Q8 industrial connector on both ends is rated for the 4 sqmm conductor cross-section, suitable for distributing 24 VDC power and up to 4 A per pin in a typical ET 200X segment. When ordering, specify the cable length in 10 cm increments within the 3 m to 5 m range.
Sourcing and Lifecycle
This is a length-specific, made-to-order cable — the factory produces it to the ordered length, so lead time reflects the manufacturing cycle rather than off-the-shelf availability. Sourcing is quoted to order against an RFQ.
