S7-300 rail switch, 24 VDC, 0.1 A draw
The Siemens 6AG1204-2BB10-4AA3 is a compact industrial Ethernet switch designed to snap onto the S7-300 mounting rail, drawing 0.1 A from a 24 VDC supply. It handles 10/100 Mbit/s transfer rates and supports ring redundancy, making it a fit for control cabinets where the PLC rack and network switch share the same rail and power bus.
Protocol stack for field access and diagnostics
This switch supports CLI, DCP, FTP, SSH, HTTP, HTTPS, Telnet, SNMP v1/v2/v3, DHCP client, LLDP, SNTP, TFTP, SMTP server, and MIB — covering remote configuration, file transfer, trap forwarding via email, and port diagnostics. The C-PLUG slot stores the configuration, so a failed unit can be swapped without re-commissioning from scratch.
IP30, compact footprint, KC approval
IP30 protection class means it's suited for dry indoor cabinet environments — no washdown or outdoor exposure. The dimensions (60 mm wide, 125 mm high, 124 mm deep) fit standard S7-300 panel layouts. KC approval covers Korean market installations.
