HIRSCHMANN RS20-1600T1T1SDAUHX    Switch

Configurator Description

Fast Ethernet Ports with/without PoE The RS20 compact OpenRail managed Ethernet switches can accommodate from 4 to 25 port densities and are

available with different Fast Ethernet uplink ports – all copper, or 1. 2 or 3 fiber ports. The fiber ports are available in multimode and/or singlemode. Gigabit

Ethernet Ports with/without PoE The RS30 compact OpenRail managed Ethernet switches can accommodate from 8 to 24 port densities with 2 Gigabit ports

and 8. 16 or 24 Fast Ethernet ports. The configuration includes 2 Gigabit ports with TX or SFP slots.

Hirschmann RS20-1600T1T1SDAUHX (Order Code / Configured Variant of the OpenRail RS20 family) is a high-density, 16-port Fast Ethernet unmanaged industrial DIN-rail switch engineered by Belden/Hirschmann. Built for harsh automation, energy, and transportation environments, it provides reliable plug-and-play connectivity without requiring software configuration.

1. Unique Product Description

The RS20-1600T1T1SDAUHX stands out in industrial networking due to its 16-port copper density on a compact DIN-rail footprint paired with industrial-grade hardening:

Configured Part Number Breakdown:

RS20: OpenRail Fast Ethernet Compact Series.

1600: 16 Fast Ethernet (10/100 Mbps) ports total.

T1T1: Uplinks are Twisted Pair / RJ45 copper.

SD: Standard 12/24/48 VDC power input range with redundant terminals.

A: Standard approvals (CE, cUL508).

U: Unmanaged Software Class (plug-and-play, no Web/SNMP configuration needed).

HX: Factory-customized hardware variant/packaging code (often indicating specific hardware revisions or extended testing).

2. Product Advantages and Features

High-Density Port Layout: Provides 16 × 10/100BASE-TX RJ45 ports in a single compact DIN-rail unit, minimizing cabinet footprint.

True Plug-and-Play (Unmanaged): Requires zero network configuration, reducing commissioning time and maintenance complexity.

Fanless & Solid-State Reliability: Passive convection cooling with no moving parts ensures long operational lifespan (MTBF over 40 years).

Dual Redundant Power Inputs: Accepts primary and backup DC power lines (9.6 V DC to 60 V DC) to prevent single point of failure outages.

Integrated Signaling Contact: Features a hardware fault relay output to alert PLCs or alarm indicators if a power line drops.

Auto-Crossing & Auto-Negotiation: Automatically detects cable types (MDI/MDI-X crossover) and port speeds for hassle-free device connection.

3. Application Cases

Manufacturing & Assembly Lines: Connecting dozens of localized PLCs, sensors, drives, and HMIs to a central network drop without needing managed switch complexity.

Building Automation & Security: Aggregating IP security cameras, access control hardware, and HVAC controllers across facility panels.

Energy & Utility Cabinets: Field-deployed control cabinets requiring wide operating voltage tolerances and vibration resistance.

Machine OEM Skids: Compact integration inside standalone industrial machinery where factory personnel need straightforward hardware replacement without software setup.

4. Installation and Maintenance

Installation

DIN Rail Mounting: Hook the top clip of the switch onto a standard 35 mm DIN rail and push down until it snaps securely.

Grounding: Connect the chassis grounding screw directly to the cabinet panel earth line to shield against industrial EMI/ESD.

Power Wiring: Connect dual DC power feeds (e.g., 24 V DC) to the 6-pin removable terminal block.

Cabling: Plug in standard RJ45 Cat5e/Cat6 copper Ethernet cables (up to 100 meters length per segment).

Maintenance & Diagnostics

Status LEDs:

P1 / P2: Green indicates active power supply on respective channel.

Fault/Signal LED: Lights up if one power line is lost.

Port LEDs (Link / Data): Flashing green indicates link detection and active network traffic.

Zero Maintenance: Being an unmanaged switch, there are no firmware updates or configuration files to back up or restore. Device replacement is purely physical swap-out.
