SIEMENS SIMATIC Base Unit Type B0, BU20-P12+A4+0B Bangladesh. Mlfb - 6ES7193-6BP20-0BB0 price

 The Siemens SIMATIC ET 200SP Base Unit BU20-P12+A4+0B, 6ES7193-6BP20-0BB0, is a Type B0 Base Unit designed for compatible ET 200SP I/O configurations. Siemens specifies push-in terminals, 12 process terminals and four AUX terminals bridged to the left. The unit has a 20 mm width, 117 mm height and 35 mm depth, with an approximate weight of 48 g. The Type B0 design is associated with supply over the P1/P2 busbar, and Siemens documentation specifies 24 V DC nominal values for the P1/P2 bus, AUX bus and process terminals, with corresponding AC ratings documented in the manual. This Base Unit is therefore distinct from the 15 mm-wide Type A0/A1 Base Units and should be selected according to the exact I/O module and station configuration.

5. Product Highlights

The 6ES7193-6BP20-0BB0 differs from the 15 mm Type A0/A1 Base Units by using a 20 mm-wide Type B0 architecture with 12 process terminals and four AUX terminals. Its P1/P2 bus supply architecture and left-bridged AUX arrangement are important selection criteria for compatible ET 200SP configurations.

6. Important Ordering & Installation Information

Confirm Type B0 compatibility before ordering. This Base Unit is not interchangeable with Type A0 or A1 Base Units merely because they belong to the same ET 200SP family. Verify the selected I/O module, P1/P2 supply architecture, AUX requirements, process-terminal current and installation altitude. Siemens documentation specifies maximum installation altitude of 2,000 m unless otherwise arranged.  

Always follow the manufacturer's official installation, wiring, commissioning and safety instructions.

7. Why Choose Siemens SIMATIC ET 200SP Base Unit BU20-P12+A4+0B 6ES7193-6BP20-0BB0?

The 6ES7193-6BP20-0BB0 is suitable when the ET 200SP system requires the specific Type B0 architecture, 12 process terminals, four AUX terminals and P1/P2 bus supply arrangement. Its 20 mm width and defined terminal structure provide a clear match for compatible Type B0 I/O configurations.

8. Product Summary

The Siemens 6ES7193-6BP20-0BB0 is a SIMATIC ET 200SP Type B0 Base Unit with BU20-P12+A4+0B configuration. It uses push-in terminals, provides 12 process terminals and four AUX terminals, and has the AUX terminals bridged to the left. The Base Unit is 20 × 117 × 35 mm and weighs approximately 48 g. Siemens documentation specifies maximum P1/P2 bus current of 10 A and maximum process-terminal current of 5 A. It uses the Type B0 P1/P2 bus supply architecture and is intended for compatible ET 200SP I/O modules. Exact Type B0 compatibility should be confirmed before ordering or replacement.
