6ES7193-6BP20-0BA0 ET 200SP BaseUnit BU15-P16+A10+2B Type A0 | Siemens

The Original New Siemens 6ES7193-6BP20-0BA0 SIMATIC ET 200SP BaseUnit BU15-P16+A10+2B is a Type A0 base unit (BU) for the ET 200SP distributed I/O system. It serves as the mechanical and electrical foundation for ET 200SP I/O modules, providing the connection between the module and the backplane bus. Featuring Push-In terminals for tool‑free wiring, this 15 mm wide base unit supports 16 process terminals and 10 AUX terminals, bridged to the left to continue the potential group from the left side. Compatible with all I/O modules of BaseUnit type “A0”.

Core Engineering Highlights:
15 mm width | BU type A0 | 24V DC nominal supply voltage | 10A current carrying capacity for P1/P2 bus and AUX bus | 2A for process terminals | Push-In terminals | 16 process terminals + 10 AUX terminals | Bridged to the left | No new potential group | 1 slot for I/O module | 141 mm height | –30°C to +60°C horizontal / –30°C to +50°C vertical | IP20 protection
