What It Is and Where It Lands
The 6ES7193-6BP00-2DA0 is a SIMATIC ET 200SP BaseUnit, BU type A0. It provides the mechanical and electrical interface between an I/O module and the backplane bus in an ET 200SP distributed I/O system. The BaseUnit carries 16 process terminals to the I/O module, plus two terminals connecting to the and bus rails.
Key Ratings and Their Meaning for Fit
The and bus bars are rated for a maximum of 10 A; the process terminals are rated for a maximum of 2 A. That 10 A figure governs the total current you can draw through the bus from this BaseUnit to the module above it — important when planning the supply for a multi-slot rack. The 2 A per process terminal is the limit for the I/O module's load or sensor circuits. External protection for the 24 V DC supply line must be a miniature circuit breaker with type B or C tripping characteristic, rated at 10 A. Operating temperature range depends on orientation: horizontal installation allows -30 °C to 60 °C; vertical installation derates the maximum to 50 °C. Maximum installation altitude is 5 000 m, with restrictions above 2 000 m. The unit is isolation-tested at 707 V DC (type test).
Integration Notes for the Panel Builder
The BaseUnit snaps onto a DIN rail and accepts one I/O module in its single slot. The slot is keyed for Type A0 modules — verify the I/O module's compatible BaseUnit type in its datasheet. The hardware functional status is from FS06; check compatibility with older firmware revisions of the ET 200SP interface module. An optional system-integrated shield connection is available for the process terminals. The BaseUnit does not continue the potential group from the left, so it always starts a new group. Process terminals are assigned for CC00 to CC09 color-coded I/O modules.
Sourcing and Lifecycle
The 6ES7193-6BP00-2DA0 is listed as active in production. It is sourced to order against an RFQ through standard Siemens distribution channels. There is no official successor or second-source replacement — this is the current part for new designs requiring a Type A0 BaseUnit with push-in terminals.
