BELDEN RS30-0802T1T1SDAP / RS300802T1T1SDAP Fully Managed Layer 2 Compact Rail Switch
BELDEN RS30-0802T1T1SDAP / RS300802T1T1SDAP
Hirschmann RS30-0802T1T1SDAP (also written as RS300802T1T1SDAP, Belden Order Code: 943 434-030) is a heavy-duty, highly resilient Layer 2 Managed Industrial Ethernet Switch engineered for harsh, high-vibration plant environments.
As a cornerstone of the established OpenRail family, this switch features an advanced, fanless design that provides 10-port versatility—specifically balancing eight Fast Ethernet lines with two high-speed Gigabit Ethernet uplink ports.
Outfitted with Hirschmann’s proprietary Professional (P) software package, the RS30-0802T1T1SDAP delivers robust industrial profile integration (including PROFINET and EtherNet/IP), sophisticated diagnostic frameworks, and industry-standard redundancy algorithms.
It ensures deterministic, near-zero-latency communication loops across modern factory grids, high-voltage substations, and infrastructure control systems.
Unique Product Description
The Belden Hirschmann RS30-0802T1T1SDAP is a compact, DIN-rail mounted industrial managed switch equipped with 8 standard 10/100BASE-TX RJ45 ports and 2 standalone Gigabit Ethernet 10/100/1000BASE-TX RJ45 uplink ports.
Unlike basic media variants, this particular model relies completely on copper interfaces across its entire 10-port block, eliminating the need for optical transceiver add-ons when creating high-bandwidth backbone lines within a compact local cell.
Housed in a rugged, passively cooled IP20 chassis, this switch implements a dependable Store-and-Forward architecture to maintain maximum structural packet integrity.
Backed by Hirschmann’s signature “HIPER-Ring” topology and Media Redundancy Protocol (MRP), the RS30-0802T1T1SDAP handles link disruptions seamlessly with recovery intervals measured in milliseconds.
Dual-channel terminal inputs (supporting 12V to 48V DC grids) and comprehensive command-line and web interface management make this switch an indispensable pillar for secure, scalable, and noise-immune automation architectures.
