Siemens 6ES7193-6BP00-0BA0 SIMATIC ET 200SP BaseUnit BU15-P16+A0+2B Type A0 24V DC Remote I/O Accessory

The Siemens 6ES7193-6BP00-0BA0 is a SIMATIC ET 200SP BaseUnit, type A0, that carries a digital I/O module on a 24 V DC potential group bridged in from the terminal to its left. It provides 16 push-in process terminals across a 15 x 117 mm footprint and passes up to 10 A on the P1/P2 backplane bus.

Selection Notes

This BaseUnit bridges its potential group in from the terminal on its left, so it shares the 24 V supply and reference potential of the preceding BaseUnit in the row - use it for modules that stay on the same load group as their neighbor. Pick a new-potential-group BaseUnit instead when a module needs its own fresh 24 V group at that position, for example downstream of outputs that must be individually fused or isolated. The push-in terminals accept 0.14-2.5 mm² (AWG 26-14) conductors, and the 10 A external circuit breaker requirement on the supply line sets the practical current ceiling for the whole potential group, not just this base.

Applications

Mounts in a SIMATIC ET 200SP station to carry a Type A0 digital I/O module (16 process terminals) sharing a bridged 24 V DC potential group with the adjacent station position - typical in mixed digital I/O racks where several modules run off one supply feed.
