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

6ES7193-6BP00-0BA0 is the SIMATIC ET 200SP Base Unit BU15-P16+A0+2B (BU Type A0), a compact base for the ET 200SP distributed I/O family with a WxH footprint of 15 x 117 mm and push-in terminals designed for quick wiring. This base unit, identified by article number 6ES7193-6BP00-0BA0, uses the BU15-P16+A0+2B configuration and is classed as BU Type A0, featuring no AUX terminals and a left-hand bridge arrangement. It provides the mechanical and electrical interface for mounting ET 200SP I/O modules and supports the P16 power distribution bus (CC00 to CC05) for straightforward stacking of modules in space‑constrained installations. For protection of the power-supply lines, Siemens specifies external protection, including a 24 V DC input backed by a 10 A miniature circuit breaker of type B or C as a typical protective device, ensuring safe operation in industrial environments. The BU is designed to integrate seamlessly with the ET 200SP system, delivering reliable modular expansion and a compact footprint suited for control cabinets, while maintaining compatibility with SIMATIC industrial automation protocols and onboard diagnostics through the ET 200SP ecosystem.
