The Hirschmann RSP30-08033O6TT-SK9V9HSE2S is a hardened managed fanless DIN rail switch from the Hirschmann RSP30 series, offering eleven switching ports with eight 10/100BASE-TX RJ45 copper ports and three dual-speed SFP slots supporting 100 or 1000 Mbit/s connections via compatible M-SFP modules. It is the high-voltage power supply variant of the RSP30-08033O6TT series, accepting a single 60–250 VDC (48–320 VDC range) and 110–230 VAC (88–265 VAC) power input via a plug-in terminal block, making it directly usable with the high-voltage AC or DC distribution systems common in substations, power plants, and large industrial facilities. Power consumption is 15 W. The software and redundancy feature set is identical to the dual 24 VDC variant, including PRP per IEC62439-3, HSR, Fast MRP, RSTP, LACP link aggregation, and link backup for comprehensive network resilience. Industrial protocols include PROFINET, IEC61850 MMS server, EtherNet/IP, and Modbus TCP. Switching, security, diagnostics, configuration, and time synchronisation capabilities follow the full RSP30 specification including IGMP snooping, VLAN, QoS, 802.1X, RADIUS, HTTPS, SSHv2, SNMP v1/v2/v3, PTPv2, and ACA31 SD card autoconfiguration. IEC 61850-3 and IEEE 1613 substation certification, CE, FCC, EN61131, and a 60-month guarantee confirm its suitability for utility and industrial infrastructure with high-voltage power distribution.
