Request a... Price & Availability It features 4 twisted-pair (TX) ports with 10/100 Mbps auto-negotiation and one 100 Mbps single-mode fiber (FX) port with SC connector, providing long-distance connectivity up to 20 km. The switch supports redundant power supply (24 V DC) and offers an extended operating temperature range from -40°C to +70°C, making it suitable for outdoor and demanding applications. This switch is fully managed, supporting advanced network features such as VLANs, Quality of Service (QoS), IGMP snooping, and Rapid Spanning Tree Protocol (RSTP). It also includes a web-based management interface and supports SNMP for integration into larger network management systems. The SPL20 series is known for its compact metal housing, DIN rail mounting, and compliance with industrial standards like IEC 61850-3 and IEEE 1613 for substation automation. The EEC suffix indicates the extended temperature range and conformal coating on the PCB, providing protection against moisture, dust, and corrosive gases. This makes the SPL20-4TX/1FX-SM-EEC ideal for use in transportation, oil and gas, and power utility applications where reliability and longevity are critical. With its robust design and comprehensive management features, this switch ensures high network availability and performance in mission-critical industrial networks. The Hirschmann SPL20-4TX/1FX-SM-EEC is a managed industrial Ethernet switch from the Spider II family, designed for reliable data communication in harsh industrial environments. Basic Product Information 1 x 100BASE-FX single-mode fiber port with SC connector (20 km reach) Extended temperature range: -40°C to +70°C Conformal coating for protection against harsh environments Redundant power supply input (24 V DC) Web-based management, SNMP, VLAN, QoS, IGMP snooping, RSTP 4 x 10/100BASE-TX RJ45 ports with auto-negotiation and auto-crossing Technical Specifications Version & Model Difference The SPL20-4TX/1FX-SM-EEC is part of the Spider II family. Compared to the standard SPL20-4TX/1FX (without EEC), the EEC version includes conformal coating on the printed circuit board and an extended temperature range (-40°C to +70°C) instead of the standard -40°C to +60°C. The EEC version is designed for more demanding environments where humidity, condensation, and corrosive gases are present. Other variants include the SPL20-4TX/1FX-MM (multi-mode fiber) and SPL20-4TX/1FX-SM (single-mode without conformal coating). Application Scenarios Can the SPL20-4TX/1FX-SM-EEC be used for fiber optic connections over long distances? Yes, the single-mode fiber port supports distances up to 20 km when using 9/125 µm single-mode fiber. This makes it suitable for connecting remote sites or devices spread over large areas. Does this switch support Power over Ethernet (PoE)? No, the SPL20-4TX/1FX-SM-EEC does not support PoE. It is a standard managed Ethernet switch that requires separate power for connected devices. What management features are available on this switch? The switch offers a web-based interface for configuration, as well as support for SNMP (v1/v2c/v3), VLAN (IEEE 802.1Q), QoS (IEEE 802.1p), IGMP snooping, Rapid Spanning Tree Protocol (RSTP), and port mirroring. It also supports firmware updates via TFTP/HTTP. What is the difference between the SPL20-4TX/1FX-SM and the SPL20-4TX/1FX-SM-EEC? The EEC version includes conformal coating on the PCB and an extended operating temperature range of -40°C to +70°C, compared to the standard version which has a range of -40°C to +60°C. The conformal coating protects against moisture, dust, and corrosive gases.
