Siemens SIMATIC ET 200SP 6ES7193-6BP00-0BA0 Base Unit

Product Overview

The Siemens 6ES7193-6BP00-0BA0 is a BaseUnit BU15-P16+A0+2B for the SIMATIC ET 200SP distributed I/O system. It provides the mechanical mounting, electrical backplane connection, and field wiring terminals for one Type A0 I/O module. With 16 push-in process terminals, no auxiliary terminals, and bridged potential to the left, it is the standard, cost-effective foundation for ET 200SP digital and analog I/O modules.

Compatibility & Applications

Compatible with all ET 200SP Type A0 I/O modules (DI, DO, AI, AO, technology modules). The default choice for automotive welding cells, packaging machines, material handling systems, and general automation where auxiliary power distribution is not required.

FAQ

• Q: What does "bridged to the left" mean? A> The P1/P2 power bus continues from the adjacent left BaseUnit without creating a new potential group. Use 6ES7193-6BP00-0DA0 to start a new potential group.
• Q: Can I use this with safety I/O modules? A> Yes, the BaseUnit is compatible with ET 200SP safety modules. Verify the safety module specifies Type A0 BaseUnit compatibility.
• Q: What is the difference between 0BA0 and 0DA0? A> 0BA0 bridges potential to the left. 0DA0 starts a new potential group (new load group). Select based on your power segmentation strategy.
• Q: Is external circuit protection required? A> Yes, a 10 A Type B or C miniature circuit breaker must be installed upstream. The BaseUnit has no internal overcurrent protection.

Installation Guide

1. Mount the BaseUnit on the ET 200SP DIN rail (35 × 7.5 mm or 35 × 15 mm).
2. Slide the BaseUnit horizontally until it clicks into place.
3. Insert the I/O module into the BaseUnit slot until fully seated.
4. Connect field wiring to the push-in terminals (strip 6–8 mm, insert until click).
5. Verify all conductors pass a gentle tug-test.

Selection Tips

• Use 6ES7193-6BP00-0BA0 as the default BaseUnit for standard ET 200SP Type A0 I/O modules.
• For applications requiring auxiliary terminal distribution, use 6ES7193-6BP20-0BA0 (10 AUX terminals).
• To create a new potential group (power segmentation), use 6ES7193-6BP00-0DA0 instead.
• Verify conductor sizes fall within 0.14–2.5 mm² before specifying push-in terminals.
