The Siemens 6ES7193-6AP20-0AA0 is a SIMATIC ET 200SP Bus Adapter BA SCRJ/RJ45 that provides media conversion between an SCRJ fiber-optic connection and an RJ45 connection. Siemens identifies the device as having one SCRJ FO connection and one RJ45 connection, with one PROFINET interface containing two ports.

The adapter supports PCF, plastic FOC/POF, PCF-GI, and copper connections with Siemens-specified cable-length limits. It is intended for compatible ET 200SP CPU/interface modules where a fiber-to-copper PROFINET connection is required.

5. Product Highlights
The 6ES7193-6AP20-0AA0 is specifically useful where an ET 200SP PROFINET station must bridge SCRJ fiber-optic and RJ45 copper connection technologies. Its mixed-interface design eliminates the need to select a purely fiber or purely RJ45 Bus Adapter when both media are required at the connection point.
6. Important Ordering & Installation Information
Confirm that the selected ET 200SP CPU/interface module supports the BA SCRJ/RJ45 Bus Adapter. Before installation, verify the fiber type, connector type, and required cable distances because Siemens specifies different maximum lengths for PCF, POF, PCF-GI, and copper cable.
The Bus Adapter is used as part of the compatible ET 200SP CPU/interface-module assembly. Fiber termination and copper Ethernet connection must follow Siemens' applicable installation documentation.
Always follow the manufacturer's official installation, wiring, commissioning and safety instructions.
7. Why Choose Siemens 6ES7193-6AP20-0AA0?
The Siemens 6ES7193-6AP20-0AA0 is suitable for ET 200SP installations that require a defined SCRJ-to-RJ45 PROFINET media conversion interface. Its mixed physical interfaces and compact dimensions support integration of fiber-optic and copper network segments within compatible industrial automation architectures.
8. Product Summary
Siemens 6ES7193-6AP20-0AA0 is a SIMATIC ET 200SP Bus Adapter BA SCRJ/RJ45 providing one SCRJ fiber-optic connection and one RJ45 connection. It provides one PROFINET interface with two ports and supports PCF, POF, PCF-GI, and copper cabling within Siemens-specified cable-length limits. The product measures 20 × 69.5 × 59 mm and weighs approximately 50 g. It is intended for compatible ET 200SP CPU/interface modules where fiber-to-copper PROFINET media conversion is required.
