Weidmuller 1504340000 IE-SW-BL05T-1GT-4GTPOE Gigabit PoE Unmanaged Switch

Providing high-performance Gigabit connectivity in harsh electromagnetic environments, the Weidmuller IE-SW-BL05T-1GT-4GTPOE (part number 1504340000) unmanaged industrial Ethernet switch integrates Power over Ethernet (PoE+) capabilities to streamline field device deployment. This ruggedized network switch features four Gigabit PoE+ ports and one Gigabit standard uplink port, delivering reliable data transmission and power distribution over a single cable to compatible field devices.

Key Features

• Four 10/100/1000BaseT(X) PoE+ ports and one 10/100/1000BaseT(X) RJ45 uplink port.
• Extended operating temperature range of -40 to 75 degC for deployment in extreme climates.
• Redundant dual power inputs (12/24/48 V DC) to maximize network availability.
• Robust IP30-rated aluminum housing designed for space-constrained DIN rail installations.
• Jumbo frame support up to 10 KB to optimize high-bandwidth data transfers.
• Store-and-Forward switching architecture with an 8 K MAC address table.

Industrial Applications

• IP Video Surveillance: Powering and networking high-definition security cameras in outdoor or industrial perimeters.
• Factory Automation: Aggregating high-speed data from PLCs, HMIs, and distributed I/O blocks on the factory floor.
• Traffic Control Systems: Reliable data backhaul and power delivery for roadside sensors and signaling equipment.

Empirical Engineering Insights

Alternative Models & Compatibility

The T-suffix in the model designation indicates an extended temperature rating (-40 to 75 degC), making it a direct drop-in replacement for standard-temperature variants in harsh environments. It is fully backward compatible with standard 10/100 Mbps Fast Ethernet devices, automatically negotiating speed and duplex settings.

Application Pitfalls & Engineering Notes

Be mindful of the switch's high inrush current of 17.4 A at 24 V DC during startup (lasting up to 1 ms). Ensure upstream power supplies and circuit breakers are sized to handle this transient load without tripping or causing voltage sags that could affect adjacent control hardware.

Commissioning & Wiring Tips

To achieve true power redundancy, connect the two removable 2-pole terminal blocks to separate, independent industrial power supplies. Always ground the switch housing using the integrated grounding screw to minimize electromagnetic interference and protect internal circuitry from electrostatic discharge.
