Siemens 6GK5626-2GS00-2AC2 SCALANCE SC626-2C 6-Port Industrial Security Appliance Firewall Router

The Siemens SCALANCE SC626-2C (6GK5626-2GS00-2AC2) is an industrial security appliance with four fixed 10/100/1000 Mbit/s RJ45 ports plus two RJ45/SFP combo ports, combining a stateful-inspection firewall with NAT/NAPT translation and an OpenVPN client for SINEMA RC remote access. It adds ring redundancy (MRP, HRP, RSTP) beyond basic standby switchover, and runs from a redundant 24 V DC supply rated 9.6-31.2 V.

Selection Notes

The SC626-2C's six network ports (four fixed RJ45 plus two RJ45/SFP combo) make it the choice when several sub-networks or a small ring segment need separating from one appliance, rather than protecting a single machine with a lower-port-count model in this series. It adds ring redundancy protocols (MRP, HRP, RSTP) alongside standby switchover, so it fits a topology where the security appliance itself sits in a ring rather than a single point-to-point link. Redundant 9.6-31.2 V DC feeds with an independent 13.2 W draw on each input keep it powered through a single supply-loop fault.

Applications

Perimeter firewall and secure remote-access gateway for a machine group or several sub-networks on a PROFINET/Ethernet ring, where SINEMA RC-based remote maintenance and PROFIsafe-compliant network separation are required.
