Teltonika TSW304 4-Port Gigabit Ethernet Switch for Industrial DIN Rail Applications

The Teltonika TSW304 is an ultra-compact industrial Gigabit Ethernet switch designed for space-constrained automation environments. With four 10/100/1000 Mbps ports and integrated DIN rail mounting, it delivers reliable network connectivity in server cabinets, control panels, and field enclosures where traditional switches cannot fit. The unmanaged architecture eliminates configuration overhead while aluminum construction and extended temperature tolerance ensure operation in demanding industrial conditions. Built for simplicity and durability, the TSW304 combines plug-and-play deployment with industrial-grade resilience. Its wide DC/AC power input range and optional passive PoE support reduce installation complexity, while shock-resistant housing and IP30 protection safeguard against vibration, dust, and temperature extremes. Whether connecting PLCs, IP cameras, or building management systems, the TSW304 provides Gigabit performance in the smallest footprint available from Teltonika Networks. Best For The TSW304 serves industrial automation, transportation infrastructure, and building management applications where compact Gigabit switching is essential: - Industrial Automation Panels: Connect PLCs, HMIs, and sensors in control cabinets with limited space and DIN rail infrastructure - Transportation Systems: Deploy in rail stations, traffic control boxes, and transit facilities requiring extended-temperature switching - Energy and Utilities: Aggregate SCADA devices, RTUs, and meters in substations and remote monitoring sites - Building Management: Network IP cameras, access controls, and HVAC systems in equipment rooms and IDF closets - Edge Surveillance: Connect multiple IP cameras in outdoor enclosures where unmanaged simplicity and passive PoE input are preferred Key Features - Four 10/100/1000 Mbps RJ45 ports with auto MDI/MDIX for flexible cabling and backward compatibility with legacy 10/100 devices - 8 Gbps non-blocking switching fabric with 128 KB packet buffer and 9216-byte jumbo frame support for high-throughput applications - Integrated DIN rail mounting bracket installs in standard 35 mm rails without additional hardware or mounting kits - Wide input voltage range (7-57 VDC / 9-40 VAC) plus passive PoE input on ETH1 (Mode B, 9-30 VDC) for diverse power sources - Extended operating temperature (-40°C to 75°C) and IP30-rated aluminum housing withstand extreme industrial environments - Ultra-low power consumption (idle < 0.26 W, max < 1.44 W) minimizes heat generation and energy costs - Optional PROFINET Class A conformance (order code dependent) supports industrial automation protocols - Plug-and-play unmanaged operation with auto-negotiation and 2K MAC address table eliminates configuration requirements Quick Specs Ethernet Ports 4 × RJ45 Gigabit (10/100/1000 Mbps) Switching Capacity 8 Gbps non-blocking Packet Buffer 128 KB MAC Address Table 2K entries Jumbo Frame 9216 bytes Power Input 7-57 VDC / 9-40 VAC via 2-pin industrial socket Passive PoE input: ETH1 Mode B, 9-30 VDC Power Consumption Idle: < 0.26 W, Max: < 1.44 W Operating Temperature -40°C to 75°C Humidity 5% to 95% non-condensing Enclosure Rating IP30 Housing Material Aluminum Dimensions (W×H×D) 102 × 25 × 81.5 mm (4.0 × 1.0 × 3.2 in) Weight 210 g Mounting Integrated DIN rail bracket (35 mm) Wall/surface mount (kit required) Management Unmanaged Standards IEEE 802.3i/u/ab/x/az What's Included - TSW304 Gigabit Ethernet switch - Quick Start Guide (QSG)
