6ES7193-6BP20-0DA0 ET 200SP BaseUnit BU15-P16+A10+2D Type A0 | Siemens

The Original New Siemens 6ES7193-6BP20-0DA0 SIMATIC ET 200SP BaseUnit BU15-P16+A10+2D 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, configured as a new load group (not bridged to the left or right). 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 | New load group (isolated, no bridge to adjacent BaseUnit) | 1 slot for I/O module | 141 mm height | –30°C to +60°C horizontal / –30°C to +50°C vertical | IP20 protection
