Weidmuller 1504390000 (IE-SW-VL05MT-3TX-2ST) Managed Industrial Ethernet Switch

Product Overview

The Weidmuller 1504390000 (IE-SW-VL05MT-3TX-2ST) is a high-performance, managed Industrial Ethernet switch engineered for robust data distribution in extreme environments. Part of the Value Line series, this switch features a versatile port configuration consisting of three 10/100BaseT(X) copper ports and two 100BaseFX multimode fiber ports with ST-Duplex connectors. Designed for mission-critical applications in wind power, smart grids, and heavy manufacturing, the 1504390000 supports advanced management features such as Ring redundancy and VLANs to ensure maximum network availability. Its wide operating temperature range (-40 to 75 deg C) and metal IP30 housing make it a reliable choice for decentralized control cabinets where environmental stability cannot be guaranteed.

Technical Configuration

The IE-SW-VL05MT-3TX-2ST utilizes a "Store and Forward" data switching architecture, ensuring that only valid, error-free packets are transmitted across the network. With a 2 K MAC address table and a 1 Mbit packet buffer, it efficiently manages localized traffic without congestion.

The integration of two ST-Duplex multimode fiber ports allows for reliable long-distance transmission up to 5 km, effectively bypassing electromagnetic interference (EMI) that typically degrades copper-based signals in motor control centers. For power reliability, the switch is equipped with a removable 6-pin terminal block supporting redundant 12/24/48 VDC inputs. This redundancy ensures that the network remains active even if one power circuit fails. The managed firmware provides industrial-grade features including IGMP snooping, port-based VLANs, and various ring protocols for sub-20ms recovery times in the event of a network loop break.

Technical FAQs

Q1: What are the benefits of the ST-Duplex fiber connectors over standard RJ45?

A1: The ST-Duplex fiber interface provides two major advantages: it extends the transmission distance to 5 km (compared to 100 m for copper) and provides total immunity to electrical noise (EMI/RFI), which is critical when routing cables near high-voltage VFDs or motors.

Q2: Does this switch support ring redundancy for high availability?

A2: Yes. As a managed switch in the Value Line, it supports various redundancy protocols, allowing the network to recover in less than 20 ms if a segment of the fiber or copper ring is damaged.

Q3: Can this module be mounted in outdoor cabinets?

A3: While the switch has an impressive operating range of -40 to 75 deg C, it is rated IP30. This means it must be installed inside a secondary NEMA 4 or IP66 rated enclosure if it is to be used in outdoor or wash-down environments.

Engineering & Installation Guide

• Fiber Optic Precision: When connecting the ST-Duplex transceivers, ensure the fiber end-faces are cleaned with an approved optical grade cleaner. Dust on a 100 Mbps fiber port can lead to significant packet loss or a complete link failure.

• Redundant Power Wiring: Utilize the 6-pin removable terminal block to connect two independent power sources (e.g., a primary PSU and a battery backup). Ensure the grounding pin is connected to the DIN rail or cabinet earth to provide a path for transient surge protection.

• Network Segmenting: Use the managed VLAN features to isolate sensitive PLC/DCS traffic from general peripheral data. This reduces the broadcast traffic processed by the 2 K MAC table and ensures lower latency for critical control packets.

Engineering Advantages

The 1504390000 is distinguished by its extreme thermal resilience, maintaining full 100 Mbps throughput at 75 deg C without the need for active cooling fans. Its "Store and Forward" switching method is specifically calibrated for industrial protocols (like PROFINET or EtherNet/IP), prioritizing data integrity over raw cut-through speed. Furthermore, the compact 53.6 mm width allows for significant port density on crowded DIN rails, while the metal housing provides the structural rigidity required for high-vibration applications such as rail transport or heavy stamping presses.
