Siemens 6ES7193-6BP20-0DA0 SIMATIC ET 200SP BaseUnit BU15 Type A0 Remote I/O Accessory

The Siemens 6ES7193-6BP20-0DA0 is a SIMATIC ET 200SP BaseUnit, type A0, model BU15-P16+A10+2D, that starts a new potential group on the station. It provides push-in terminals for 16 process connections and 10 AUX-bus terminals, rated 10A on the P1/P2 and AUX bus and 2A per process terminal, so one BaseUnit both isolates the module electrically and starts a fresh load group downstream.

Selection Notes

This BU15-P16+A10+2D variant starts a new potential group, so use it where the next I/O module needs isolation from the previous load group's 24V supply rather than continuing it. It provides 10 AUX-bus terminals for wiring sensor supplies or third-wire signals alongside the 16 process terminals, and the 10A P1/P2 and AUX bus rating, protected externally by a 10A type B/C breaker, sets the group's current budget before the next new-potential-group BaseUnit is needed.

Applications

Load-group segmentation and I/O module mounting on SIMATIC ET 200SP stations where a module needs its own 24V potential group and AUX-bus wiring.
