The Hirschmann RSP20-11003Z6TT-SK9V9HSE2S is a managed DIN rail industrial Fast Ethernet switch within the RSP20 series, combining eight 10/100 Mbit/s copper RJ45 ports with three SFP fibre slots in an 11-port mixed-media configuration, and distinguished by its wide-range AC/DC power input accepting 60–250 VDC or 110–230 VAC, making it directly compatible with substation AC power buses and high-voltage DC distribution systems without external power conversion hardware. Running HiOS Layer 2 firmware, the switch delivers the same comprehensive redundancy and management feature set as other RSP20 variants, including PRP and HSR per IEC 62439-3 for seamless zero-downtime failover, MRP per IEC 62439-2, RSTP, and LACP, alongside advanced VLAN management, QoS, IGMP snooping, and jumbo frame support. Industrial protocol coverage includes PROFINET, EtherNet/IP, Modbus TCP, and IEC 61850 MMS server and switch model, with PTPv2 transparent and boundary clock and 802.1AS time synchronisation for precision timing. Security features encompass 802.1X port access control, RADIUS, MAC-based port security, signed firmware images, VLAN-based ACLs, and comprehensive audit trail and logging capabilities. The SFP slots support single-mode, long-haul, and multi-mode fibre modules for flexible fibre reach. The 90 x 164 x 120 mm IP20 DIN rail housing withstands 35 V/m EMC immunity and IEC 60068 shock and vibration, and the switch holds IEC 61850-3, IEEE 1613, CE, FCC, and EN61131 certifications with a 60-month guarantee.
