Hirschmann SPIDER-SL-20-04T1S29999SY9HHHH Industrial Switch

Unique Product Description

The Hirschmann SPIDER-SL-20-04T1S29999SY9HHHH (Part Number: 942 132-009) is an entry-level, unmanaged 5-port Industrial Fast Ethernet switch from Belden’s SPIDER III Standard Line (SSL) series.

Featuring 4 × 10/100Base-TX RJ45 copper ports and 1 × 100Base-FX Single-Mode SC optical fiber uplink port, this compact switch extends Ethernet connectivity over distances of up to 30 km without signal degradation. Designed for plug-and-play installation in space-constrained enclosures, it operates silently using a fanless, IP30 plastic housing while maintaining minimal power consumption.

Product Advantages and Core Features

Long-Distance Fiber Link: Integrated 100Base-FX single-mode optical port (SC interface) supports reliable network links up to 30 km.

Ultra-Compact Footprint: Measuring just 26 mm × 102 mm × 79 mm, its slim housing conserves valuable space on control cabinet DIN rails.

Plug-and-Play Simplicity: Requires zero software configuration—features auto-negotiation, auto-crossing (MDI/MDI-X), and auto-polarity on all copper ports.

Low Power Consumption: Consumes a maximum of 2.4 W (100 mA @ 24 V DC), lowering energy usage and thermal output inside control cabinets.

High Operational Reliability: Rated with a Mean Time Between Failures (MTBF) exceeding 2.2 million hours.

Technical Specifications Overview

Application Cases

The SPIDER-SL-20-04T1S29999SY9HHHH is tailored for cost-sensitive, unmanaged field-level industrial networks:

Remote Sub-Panels & Machine Control: Connects field PLCs, HMIs, and drives inside remote control cabinets back to a central control room over a single-mode fiber trunk.

Building Automation & Security: Feeds data from IP cameras and access control units spread across large facilities or outdoor perimeters over long-distance optical links.

Renewable Energy (Solar/Wind Farms): Interconnects localized monitoring equipment in field combiner boxes across multi-kilometer sites where copper cabling would suffer from electromagnetic interference (EMI) or length limits.

Installation and Maintenance

Installation Procedure

Mounting: Snap the unit onto a standard 35 mm DIN rail (IEC 60715).

Wiring Power: Connect a 12/24 V DC power feed (9.6–32 V DC) to the 3-pin plug-in screw terminal block.

Cable Connections:

Plug Cat5e/Cat6 copper Ethernet cables into RJ45 ports 1 through 4.

Connect single-mode fiber cables (9/125 $\mu$m) to the SC fiber connector port (observe TX/RX polarity).

Maintenance & Diagnostics

Status LEDs: Verify operational status via front panel LEDs:

P (Power): Green = Power supply connected and within 9.6–32 V DC tolerance.

Port Link/Data: Solid Green = Active network connection; Blinking = Active data transmission.

Maintenance: Fanless construction requires no scheduled physical maintenance. Periodically inspect terminal block connections and keep optical connectors clean with fiber-cleaning tools during cable reconnects.
