Siemens 6ES7193-6BP20-0DA0 Electrical Connector

Siemens 6ES7193-6BP20-0DA0 is the ET 200SP bus connector/base unit (BU-Type A0) used to interface the ET 200SP backplane with the BU-A0 configuration. As Base Unit BU15-P16+A10+2D, it carries a 15 mm-wide footprint and measures 15 mm in width, 141 mm in height, and 35 mm in depth, matching the BU-A0 form factor. It features push-in terminals and provides 10 auxiliary (AUX) terminals for additional connections, with conductor termination suitable for 26 to 14 AWG wiring. Electrical isolation between the backplane bus and the supply side is specified up to 707 V DC in type testing, reflecting Siemens' emphasis on safe separation within the ET 200SP system. The 6ES7193-6BP20-0DA0 is intended for ET 200SP installations that require a BU-A0 base unit with dedicated auxiliary wiring and a push-in connection scheme, enabling a modular, scalable I/O architecture when combined with compatible ET 200SP I/O modules. This base unit is commonly chosen when a compact, standardized 15 mm-wide BU-A0 component is needed to extend the backplane and accommodate field wiring within Siemens' ET 200SP ecosystem.
