Siemens SIRIUS 3RA2711-0EE17 Module Connector, 6 cm, 14-Pole For 3RA27/3RA28 Function Modules Original Brand New

Overview: Siemens 3RA2711-0EE17 Module Connector

The Siemens 3RA2711-0EE17 module connector is a critical component in the SIRIUS modular system, designed for the efficient, permanent electrical and mechanical connection of various function modules. This specific connector provides a 6 cm linking distance and features a robust 14-pole design, ensuring reliable data and control signal transmission.

It is specifically engineered to interface with Siemens SIRIUS 3RA27 function modules (e.g., for IO-Link or AS-Interface) and the 3RA2816-0EW20 coupling module, facilitating quick, error-free assembly of complex motor starter combinations.

Benefits and Advantages

The 3RA2711-0EE17 offers distinct advantages for industrial automation and control panel builders:

1. Reduced Wiring Effort: Eliminates the need for individual control wiring between adjacent modules, simplifying the panel layout and reducing assembly time.
2. Increased Reliability: Provides a secure, plug-in connection that is less susceptible to vibration-induced faults compared to traditional screw or spring-cage wiring.
3. Space Efficiency: The compact 6 cm length is optimized for linking modules in close proximity, helping to save valuable space within the control cabinet.
4. Error Prevention: The coded design of the 14-pole connector ensures correct mating and polarity, virtually eliminating wiring mistakes during installation.
5. System Integration: Perfectly fits the Siemens SIRIUS modular system, ensuring seamless operation with contactors, motor starters, and fieldbus function modules (like those in the 3RA27 family).

Function: Simplifying Modular Starter Assemblies

The 14-pole 3RA2711-0EE17 module connector serves as a permanent bridge. When two compatible devices, such as a contactor and a 3RA27 function module, are mounted side-by-side, this connector plugs into the dedicated interfaces on both devices. It reliably transmits essential signals (e.g., control voltage, status feedback) from one module to the next, which is essential for integrated solutions like IO-Link enabled motor starters or AS-Interface solutions.
