Rugged Gigabit Connectivity for Tight Industrial Spaces

Teltonika’s TSW304 is a compact, unmanaged 4-port Gigabit Ethernet switch engineered for control panels and cabinets where space, power, and uptime matter. An aluminum IP30 enclosure, wide 7–57 VDC input and -40 to 75°C operating range keep links stable in harsh environments, while a non-blocking 8 Gbps fabric ensures full-speed traffic across all ports.

Key Benefits & Features

• 4× GbE RJ45: Auto-MDI/MDIX 10/100/1000 Mbps ports for flexible copper uplinks and edge devices.
• Wire-speed switching: 8 Gbps non-blocking bandwidth with jumbo frame support up to 9216 bytes for efficient payloads.
• Industrial power options: 2-pin DC input (7–57 VDC or 9–40 VAC) with passive PoE power-in via ETH1 (Mode B, 9–30 VDC) for simplified installs.
• Hardened build: -40 to 75°C, IP30 aluminum housing, integrated DIN-rail bracket for fast, secure mounting.
• Standards & compliance: IEEE 802.3i/u/ab/x/az support with CE, FCC, UKCA and other certifications for global deployments.

Ideal Use Cases

• Industrial automation panels and PLC networks needing compact GbE aggregation
• Transportation and building systems requiring extended-temperature switching
• Energy, utilities, and SCADA cabinets with DIN-rail power distribution
• IP cameras and sensors at the edge where unmanaged simplicity is preferred
