SPR20-8TX-EEC – Unmanaged 8-Port Fast Ethernet Rail Switch by Hirschman, a Belden Brand

The Hirschmann SPR20-8TX-EEC is an unmanaged Fast Ethernet DIN rail switch from the SPIDER III product family, providing eight 10/100BASE-TX RJ45 ports with auto-crossing, auto-negotiation, and auto-polarity in a robust IP40 metal housing designed for demanding industrial and safety-critical environments. Operating in store-and-forward mode with software features including ingress storm protection, QoS port prioritization per IEEE 802.1D/p, and jumbo frame support, this switch delivers more capability than a basic unmanaged device at extremely low power — just 2.6 W maximum. Redundant 12/24 V DC input (9.6 to 32 V DC) is provided via a 6-pin terminal block, while a USB interface enables straightforward configuration access. The unit operates across a full -40 to +70 °C temperature range and its compact 49 x 135 x 117 mm DIN rail enclosure houses electronics with an MTBF exceeding 3.7 million hours at 25 °C. Its certification portfolio is one of the most comprehensive in the SPIDER III range, covering ATEX Zone 2 and ISA 12.12.01 Class 1 Div. 2 for hazardous locations, DNVGL for marine and shipbuilding, EN50121-4 for railway, E1 for road transport, and the standard CE, FCC, and cUL 61010 approvals. This makes the SPR20-8TX-EEC an exceptional fit for oil and gas, offshore, marine, railway, transport, and factory automation projects across the Nordic and Baltic regions.
