Hirschmann RS20-1600T1T1 16-Port Managed Switch

Overview

The Hirschmann RS20-1600T1T1 is a compact, DIN-rail-mountable industrial Ethernet switch offering 16 all-copper RJ45 ports at 10/100 Mbit/s. This is an important distinction for anyone specifying it against other RS20 variants: the “T1T1” designation in Hirschmann’s RS20 naming convention denotes twisted-pair copper media on every port, with no single-mode or multimode fiber ports fitted on this specific model. Fiber connectivity is available on other members of the RS20 family, but a plant network segment specified around the RS20-1600T1T1 should be planned as a pure copper network from the outset.

As an experienced supply partner for Hirschmann (Belden) industrial networking equipment in Oman and the GCC, Seven Star LLC proudly supplies the RS20-1600T1T1 to automation integrators, EPC contractors, and plant controls teams across the Sultanate of Oman and the wider Gulf region. Every unit is supplied with manufacturer documentation and regional technical support – with availability and lead time confirmed at quotation.

Switching Architecture and Redundancy

The RS20-1600T1T1 is a fully managed switch built on store-and-forward switching technology, giving it the traffic-filtering and error-checking behavior expected of industrial-grade Ethernet infrastructure rather than a cheaper unmanaged switch that simply repeats traffic to every port. Management functionality includes VLAN segmentation, IGMP snooping and multicast filtering to keep multicast automation traffic from flooding unrelated network segments, port mirroring for network diagnostics, and granular port control for locking down unused or untrusted ports on the plant floor.

Network resilience is handled through Hirschmann’s media and ring redundancy protocols – including HIPER-Ring, the company’s proprietary fast-recovery ring topology – which allow multiple RS20 switches to be wired in a redundant ring so that a single cable or switch failure does not take down the network segment, with typical ring healing times fast enough to keep automation traffic flowing without a control system fault. The switch also supports redundant power inputs with a fault relay that triggers on loss of power or port-link, giving plant staff an immediate, wired alarm signal the moment either power feed or a monitored link goes down.

Engineering Design of the Hirschmann RS20-1600T1T1

The RS20-1600T1T1 is housed in a compact, ruggedized DIN-rail enclosure measuring 110 × 131 × 111 mm, small enough to fit multiple switches inside a standard control cabinet without consuming excessive panel space – Hirschmann’s RS20 platform is specifically engineered to pack up to 24 ports into roughly 4.5 inches of DIN rail across the family. The housing carries an IP20 protection rating, appropriate for installation inside an enclosed control cabinet rather than direct outdoor exposure, consistent with how these switches are deployed in real plant environments.

Power input accepts 12 VDC, 24 VAC, 24 VDC, or 48 VDC depending on the exact ordering variant, giving specifying engineers flexibility to match the switch to whatever control cabinet power rail is already standardized on site. Depending on the specific model variant, the RS20 platform is rated for either a standard 0°C to +60°C or an extended -40°C to +70°C operating range, the latter suited to unconditioned outdoor enclosures and the wider ambient temperature swings seen in Gulf-region plant environments.

Key Features

The RS20-1600T1T1 combines managed-switch functionality with Hirschmann’s industrial-hardened design, including:

• 16 all-copper RJ45 ports at 10/100 Mbit/s, with no fiber ports on this T1T1 variant.
• Store-and-forward switching with full managed functionality – VLANs, IGMP snooping, port mirroring, and port control.
• HIPER-Ring and media/ring redundancy protocols for fast network recovery from a single link or switch failure.
• Redundant power inputs with a fault relay triggered by loss of power or port-link, for immediate hard-wired alarm signaling.
• Compact DIN-rail housing (110 × 131 × 111 mm) designed to maximize port density inside a control cabinet.
• Flexible power input options – 12 VDC, 24 VAC, 24 VDC, or 48 VDC depending on variant.
• Standard or extended operating temperature range (0°C to +60°C, or -40°C to +70°C) to suit ambient conditions.
• SNMP-based network diagnostics for centralized monitoring of switch and port health from the control room.

Industrial Applications

Reliable, manageable copper Ethernet infrastructure is the backbone of nearly every modern automation system, and the RS20-1600T1T1 is built for exactly that role across Oman and the GCC’s manufacturing, power generation, and transportation facilities. On the plant floor, it connects PLCs, HMIs, variable frequency drives, and other automation devices into a single managed copper network segment, with VLAN segmentation keeping process control traffic separated from less time-critical monitoring or IT traffic on the same physical infrastructure. Where a network segment does not require fiber runs – for example, connecting devices within a single control room or a compact machine cell – the RS20-1600T1T1’s pure-copper port configuration avoids the added cost of fiber transceivers that a mixed-media switch would carry.

With fast quotation turnaround and technical support, Seven Star LLC distributes the RS20-1600T1T1 to automation integrators, EPC contractors, and plant maintenance teams across Muscat, Sohar, and Salalah, as well as the wider Gulf region. Its HIPER-Ring redundancy support makes it a natural fit for ring-topology automation networks common in power generation and process plants, where a single cable fault must never be allowed to interrupt control communication.
