Siemens Expansion module, switched Ethernet Profinet V3

Product Overview

The Siemens 7KM9300-0AE02-0AA0 is a plug-in switched-Ethernet expansion module (PROFINET V3) for the 7KM PAC series (e.g. PAC3220 / PAC4220) and compatible 3VA COM meters. It adds Ethernet / PROFINET communications capabilities to power-monitoring or energy-metering devices, allowing integration into industrial networks, remote monitoring, and data acquisition systems.

Key Features

• Switched Ethernet PROFINET expansion module (plug-in type)
• Designed for 7KM PAC3220 / PAC4220 / 3VA COM100 / 800 series devices
• 2 × RJ45 sockets for Ethernet connection (switch-integrated)
• IEC-class galvanic isolation with insulation voltage up to 500 V AC
• PROFINET IO device support with IRT, media redundancy (MRP), system redundancy
• Support for open IE communication protocols (TCP/IP, SNMP, LLDP)
• Autonegotiation and autocrossover — simplifies network wiring
• Transfer rate: 100 Mbps for RJ45 plug connection
• Mounting: plug-in to PAC / COM modules — compact module form (approx. 63 × 43 × 22 mm)
• IP20 protection rating — suitable for mounting inside enclosure or switchgear
• Wide MTBF (long-term reliability) — ideal for continuous monitoring / industrial use
