The Siemens 6ES7193-6BP20-0BB1 is a SIMATIC ET 200SP
Base Unit designated BU20-P12+A0+4B, Base Unit type B1. It
provides the electrical and mechanical connection between an ET 200SP I/O
module and the field wiring while supporting permanent wiring through the Base Unit.
The unit uses push-in terminals and is configured without auxiliary terminals,
with the potential group bridged to the left. Siemens specifies a 20 mm width
and 117 mm height for this Base Unit. The 6ES7193-6BP20-0BB1 supports rated
supply values of 24 V DC and 230 V/110 V AC depending on the relevant circuit,
with a maximum current carrying capacity of 10 A up to 60 °C. Siemens
documentation also specifies electrical separation between the backplane bus
and supply voltage, process terminals and supply voltage, and the Power bus and
supply voltage.

6. Important Ordering & Installation Information
- Order
the exact Siemens article number 6ES7193-6BP20-0BB1.
- This
Base Unit is a BU type B1 product and should be matched with
compatible ET 200SP modules.
- The
unit uses push-in terminals and has no AUX terminals.
- Siemens
documentation identifies specific functional-version limitations for some
Base Units; verify the current Base Unit functional status and module
compatibility before installation.
- Confirm
the applicable supply voltage and current requirements of the connected
I/O module and potential group.
- Installation
temperature limits depend on mounting orientation.
- Do not
substitute another ET 200SP Base Unit merely because its dimensions appear
similar. SSiemens
