Siemens 6ES7193-6BP20-0BB1 SIMATIC ET 200SP BaseUnit BU20-P12+A0+4B Type B1 Remote I/O Accessory

The Siemens 6ES7193-6BP20-0BB1 is a SIMATIC ET 200SP BaseUnit, type B1, that supplies one I/O module slot with push-in terminals rated up to 10 A on the P1/P2 potential group and 5 A per process terminal. It carries 24 V DC or 230 V AC depending on the module installed and isolates the backplane bus from the supply voltage, letting the user start a new potential group at this slot.

Technical Specifications

Selection Notes

Type B1 is delivered without auxiliary terminals and bridged to the left, so it continues the AUX-bus potential group of the preceding BaseUnit instead of starting a new one; pick an unbridged or isolating BaseUnit type instead when the station design needs to break the AUX-bus group at this slot. With 12 push-in process terminals and a 10 A P1/P2 rating, it accepts standard (non fail-safe) ET 200SP I/O modules with normal current draw; higher-current modules should be checked against this BaseUnit's 5 A per-terminal limit before assignment.

Applications

Carrying a standard ET 200SP digital or analog I/O module in a station where the AUX-bus potential group should continue unbroken from the neighboring slot, with push-in field wiring for the fastest terminal assembly.
