Hirschmann RS20-0800T1T1SDAEHH09.0.04 Managed Fast Ethernet DIN-Rail Switch, Layer 2 Enhanced

The Hirschmann RS20-0800T1T1SDAEHH09.0.04 is a managed 8-port Fast Ethernet switch built for DIN-rail installation. It performs store-and-forward switching across copper Ethernet links with redundant power support and fanless operation. The design fits industrial network cabinets and control environments requiring compact Ethernet connectivity.

- Processes and forwards Ethernet frames through store-and-forward switching to support controlled data handling across connected ports.
- Uses two uplink RJ45 interfaces and six standard RJ45 Fast Ethernet ports to organize traffic flow within compact network segments.
- Supports line and star topologies, enabling structured copper network layouts over standard twisted-pair cabling.
- Provides ring operation with HIPER-Ring support, enabling network reconfiguration behavior in supported ring architectures.

- Provides 8 total 10/100BASE-TX RJ45 ports, including 2 uplinks and 6 standard Fast Ethernet ports.
- Supports twisted-pair cable lengths from 0 m to 100 m per link.
- Operates from 12/24/48 V DC within 9.6-60 V DC and from 24 V AC within 18-30 V AC with redundant power input capability.
- Includes 1 x V.24 RJ11 interface and 1 x USB interface for AutoConfiguration Adapter ACA21-USB connection.
- Uses a compact DIN-rail form factor with IP20 protection, fanless construction, and operating temperatures from 0 °C to 60 °C.

- Managed Fast Ethernet switching for DIN-rail industrial Ethernet installations.
- Copper Ethernet network integration in control cabinets and automation panels.
- Ring, line, and star industrial network layouts using RJ45 Fast Ethernet connections.
