Product details

Deterministic PROFINET IO interface

The 6ES7155-5AA00-0AC0: Its integrated two-port switch supports IRT (isochronous real-time), MRP (media redundancy), and MRPD (media redundancy with planned duplication) for ring topologies with recovery times under 4 ms maximum cycle time. The module occupies two slots (35 mm wide) and draws 4.5 W typ. from the 24 V DC backplane. Its I2t rating of 0.09 A²·s confirms low inrush for supply protection sizing. This part is in current lifecycle stage and is available through our global procurement network. Firmware V4.4 supports field updates to align with controller revisions.

Frequently asked questions
