Product details

The Siemens 6AG1155-5AA01-7AB0 is a SIPLUS PROFINET IO Device with an integrated 2-port switch. It supports isochronous real-time (IRT) for deterministic motion control and media redundancy (MRP) for ring-topology resiliency.

Rated at 24 V DC, typical power consumption is 4.5 W. The I²t value of 0.09 A²·s defines the energy-handling capability during inrush (max 9 A peak) — crucial for sizing the upstream fuse or PSU. IRT enables clock-synchronized data exchange down to 250 µs cycle for servo drives.

Two RJ45 ports with auto-crossing and LLDP for topology detection. Status indicators: RUN (green), ERROR (red), MAINT (yellow).

Frequently asked questions

What is the I²t rating of this device?

The I²t rating is 0.09 A²·s, which defines the energy passed during inrush current (max 9 A).

Does this device support isochronous real-time (IRT)?

Yes, it supports IRT for deterministic communication down to a shortest clock pulse of 250 µs.

What are the power supply requirements?

It requires 24 V DC, typical power consumption 4.5 W, with a maximum inrush current of 9 A.
