Facilitating reliable data distribution and power delivery in demanding industrial networks, the Weidmuller IE-SW-BL06T-4POE-2SC (part number 1504220000) functions as a robust, unmanaged Fast Ethernet switch. This unit integrates four Power over Ethernet (PoE) ports alongside two multimode fiber optic ports to bridge long-distance field communications with local IP-enabled hardware.
Key Features
-
Multi-Port Architecture: Equipped with 4 RJ45 PoE ports and 2 multimode SC-Duplex fiber ports.
-
Extended Optical Range: Supports transmission distances up to 5 km over multimode fiber.
-
Redundant Power Inputs: Dual power inputs support 12/24/48 V DC configurations to ensure continuous uptime.
-
Industrial-Grade Housing: IP30-rated aluminum enclosure designed for space-constrained DIN rail installations.
-
Store-and-Forward Technology: Optimizes data packet delivery and prevents collision propagation across the local network.
Typical Applications
- IP-based video surveillance systems in manufacturing and processing plants.
- Distributed control system (DCS) and PLC networking in municipal water treatment facilities.
- SCADA telemetry integration in remote wind, solar, or oil and gas installations.
- Traffic monitoring and intelligent transportation system (ITS) roadside cabinets.

Empirical Engineering Insights
Alternative Models & Compatibility
The IE-SW-BL06T-4POE-2SC serves as a direct drop-in replacement for older unmanaged switches within the Weidmuller BasicLine series. When migrating from non-PoE variants (such as the standard IE-SW-BL06-2SC), ensure that the power supply rating is upgraded to accommodate the additional PoE power budget required by downstream field devices.
Application Pitfalls & Engineering Notes
While the switch supports a wide input range of 12/24/48 V DC, full IEEE 802.3at/af PoE output standard compliance typically requires a stable 48 V DC input supply. Operating the switch on 12 V DC or 24 V DC inputs may limit the PoE voltage boost capability or reduce the maximum deliverable wattage per port. Always verify the total power budget of connected PDs (Powered Devices) against the available input power capacity.
Commissioning & Wiring Tips
To prevent communication drops caused by high electromagnetic interference (EMI) in motor control centers, ensure the chassis grounding screw is connected to the local DIN rail or functional earth using a minimum of 14 AWG copper wire. When deploying the SC-Duplex fiber ports, verify that the TX (transmit) port of the switch connects to the RX (receive) port of the remote media converter or switch.
Installation Guidelines
CRITICAL WARNING
De-energize all power sources before mounting, wiring, or servicing this equipment. High inrush currents (up to 64.56 A) can cause severe arcing if connections are made under load. Verify that the input voltage matches the specified range on the product label before applying power.
1
Snap the switch onto a standard TS 35 DIN rail. Ensure the DIN rail clip locks securely into place to prevent physical movement during operation.
2
Connect the functional earth ground wire to the grounding screw located on the top panel of the switch housing.
3
Wire the redundant DC power supplies to the 4-pin removable terminal block connector. Tighten the terminal screws to 0.5 Nm to prevent loose connections.
4
Insert the RJ45 Ethernet cables into ports 1 through 4, and connect the SC-Duplex fiber optic cables to ports 5 and 6.
