Product details

Montage & Integration

The 6AG1155-6AU00-2CN0: Dimensions are 50 mm wide, 117 mm high, 74 mm deep. It mounts on a DIN rail and draws 4.5 A inrush at 24 VDC; steady-state power loss is 2.4 W typical. The I²t rating of 0.09 A²·s gives a thermal limit for upstream protection selection — that’s the energy the internal electronics can absorb before risk of damage. Both ports are 100BASE-TX, full duplex, with autonegotiation and autocrossing. The integrated switch means you can chain devices without an external switch, keeping the panel clean. Link Layer Discovery Protocol (LLDP) and SNMP are enabled for network management and topology discovery.

Deterministic Communication Features

PROFINET IO Device with IRT delivers cycle times down to 250 µs with 1 µs jitter. High-performance mode: 250 µs to 4 ms in 125 µs steps. Supports isochronous mode, equidistance, prioritized startup, and MRP; MRPD is not available.

Frequently asked questions

What is the I²t rating of this bus adapter?

The I²t rating is 0.09 A²·s, which defines the thermal energy the device can withstand during fault conditions — useful for coordinating protection upstream.

What IRT performance does the 6AG1155-6AU00-2CN0 support?

It supports isochronous real-time (IRT) with high performance, cycling from 250 µs to 4 ms in 125 µs increments. Maximum jitter is 1 µs.
