What It Is & Where It Fits
The 6ES7193-6BP00-0BD0 is a spare-part BaseUnit for the Siemens ET 200SP distributed I/O system, Type D0 with a single slot. It provides the mechanical mount and electrical interconnection — AUX bus, / bus, N, FE — for a 12-terminal process I/O module in a Pro slot configuration. As a bridged-to-the-left unit, it continues the potential group from the adjacent left-side module rather than starting a new group. That is the key isolation decision: if the design requires a new group, this base unit does not create one — a different type (with New potential group = Yes) would be needed.
Integration & Panel Fit
Width 20 mm is the rail footprint driver; height 117 mm and depth 35 mm sit within the standard ET 200SP envelope. Conductor cross-section accepts 0.14 to 2.5 mm² (AWG 26 to 14) via push-in terminals, which trim wiring time compared to screw-clamp alternatives. Ambient temperature range: horizontal installation from -30 °C to 60 °C, vertical limited to 50 °C. Derate the process-terminal current to 5 A at 60 °C horizontal. Installation altitude rated to 2 000 m without restriction; higher on request.
Electrical & Bus Constraints
The base unit supports 277 V on both the AUX bus and the / bus, with a bus current maximum of 10 A. The process terminals (12 per Pro slot) carry up to 5 A, equal to the derated ambient figure. Automatic encoding (FS10 and higher) simplifies module identification without manual addressing. System-integrated shield connection is not provided on this variant; if the I/O module requires cable shielding, plan for an external shield clamp. Isolation tested at 3 100 V DC between power bus and supply voltage, and between backplane bus and supply voltage.
