Product Details

The Siemens 3RK1903-0AC10 is a specialized connection and addressing accessory designed for the AS-Interface (AS-i) bus system, specifically within the SIRIUS industrial communication and motor starter product family. It serves as a connection plug (addressing cable plug) used to link AS-i modules (such as the motor starter modules or I/O fields) to a handheld addressing device for quick configuration, troubleshooting, and network setting adjustments.

Here is the detailed product manual, parameters, advantages, precautions, and industrial applications for this component.

1. Product Description

• Product Type: AS-Interface Accessory / Connection Plug.

• Function: It acts as the physical bridge between an AS-i handheld programming/addressing unit and the addressing socket of a SIRIUS motor starter or compact module. It allows field technicians to assign or change node addresses on the network without dismantling the network wiring.

• Design Integration: It features a robust, industrial-grade connector block that fits tightly into the matching diagnostic/addressing port of Siemens motor starters, ensuring perfect contact during configuration routines.

2. Product Specifications & Parameters

3. Product Advantages

• Streamlined Field Commissioning: Allows operators to instantly assign addresses to new nodes right at the machine level, drastically cutting down on commissioning time compared to software-only assignments from a master PLC.

• Zero Disconnection Required: Technicians can address or re-address a module without disconnecting the yellow AS-i flat cable or the main $24\text{ V}$ auxiliary power line, preventing accidental disruption to neighboring nodes.

• Robust, Precise Fit: Engineered with exact physical dimensions to ensure reliable data transfer between the module's micro-contacts and the addressing tool, eliminating communication errors or contact wear.

• Optimized for Field Service: Extremely lightweight and compact, it fits easily into a standard maintenance tool kit alongside handheld programmers.

Industrial Applications

This connection accessory is primarily used during the installation, maintenance, and modification stages of automated facilities:

• Conveyor Systems & Logistics: Used to quickly configure distributed motor starters (like SIRIUS M200D or similar) mounted along lengthy packaging or baggage handling lines.

• Automotive Assembly Lines: Perfect for updating or replacing I/O blocks and proximity sensor hubs on large network rings without stopping the entire production segment.

• Control Panel Building: Enables pre-commissioning addressing of modules on the bench before the entire panel assembly is shipped to the end site.
