Siemens 6ES7193-6BP20-0BA0 SIMATIC ET 200SP BaseUnit BU15-P16+A10+2B Remote I/O Accessory

The Siemens 6ES7193-6BP20-0BA0 is a SIMATIC ET 200SP BaseUnit type A0 (BU15-P16+A10+2B) with push-in terminals for 0.14 to 2.5 mm² (AWG 26-14) conductors. It provides 16 process terminals to the I/O module plus 10 AUX terminals bridged to the left, rated 10A on the P1/P2 and AUX bus while process terminals carry up to 2A, and it operates from -30 to 60 °C horizontal mounting.

Technical Specifications

Selection Notes

The AUX bus terminals are bridged to the left, so the potential group carries through from the preceding BaseUnit without a separate jumper - relevant when several BU type A0 slots in a row need to share the same AUX potential. The push-in terminals accept 0.14 to 2.5 mm² (AWG 26-14), the usual range for ET 200SP field wiring, and the 16 process terminals match a standard 8-channel BU type A0 I/O module (8 signal + 8 return/QI, depending on module type).

Applications

Mounting base for any BU type A0 I/O module in an ET 200SP station where AUX terminal access is needed for shield, PE, or potential-group wiring.
