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

Q: What industrial environments is the TSW304 designed for?

The TSW304 is built for automation panels, PLCs, SCADA cabinets, transportation control boxes, building management systems, and edge IP camera deployments. Its -40°C to 75°C operating range, IP30-rated aluminum housing, and shock-resistant design handle extreme temperatures, vibration, and dust in factories, substations, and outdoor enclosures. The integrated DIN rail mount fits standard 35 mm rails in server cabinets and control panels.

Q: Why choose the TSW304 over other Teltonika switches?

The TSW304 is the smallest switch in Teltonika's portfolio and prioritizes space savings and simplicity over advanced features. It lacks management interfaces, PoE output, and SFP ports found in larger models, making it ideal when you need basic Gigabit aggregation in tight spaces with DIN rail mounting. Choose managed switches like TSW series variants if you require VLAN, QoS, or remote monitoring.

Q: Is the TSW304 cost-effective compared to alternatives like Moxa EDS-2005?

The TSW304 offers a single model covering the full -40°C to 75°C range and accepts both VDC and VAC input, eliminating the need for multiple SKUs or separate power adapters. This reduces inventory complexity and installation cost compared to switches requiring temperature-specific variants or fixed input voltage. Its ultra-low power draw (under 1.44 W max) also minimizes ongoing energy expenses.

Q: What systems and power sources is the TSW304 compatible with?

The TSW304 works with any 10/100/1000 Mbps Ethernet device via standard RJ45 connections and auto MDI/MDIX. It accepts 7-57 VDC or 9-40 VAC from industrial power supplies, vehicle electrical systems (12/24V), or passive PoE injectors on ETH1 (Mode B, 9-30 VDC). It does not support IEEE 802.3af/at/bt PoE standards or provide PoE output. Optional PROFINET Class A conformance requires a specific order code.

Q: Does the TSW304 require configuration before use?

No configuration is needed. The TSW304 is an unmanaged switch with plug-and-play operation that auto-negotiates speed and duplex settings. Simply connect Ethernet cables and apply power between 7-57 VDC or 9-40 VAC. The 2K MAC address table and auto MDI/MDIX handle all switching functions automatically.

Q: Can the TSW304 be powered through an Ethernet port?

Yes, the TSW304 accepts passive PoE input on ETH1 via Mode B at 9-30 VDC. This input does not comply with IEEE 802.3af/at/bt standards and requires a compatible passive PoE injector. The switch does not output PoE to connected devices. Standard powering uses the 2-pin industrial DC socket with 7-57 VDC or 9-40 VAC input.

Q: What mounting hardware comes with the TSW304?

The TSW304 includes an integrated DIN rail bracket for standard 35 mm rails, requiring no additional mounting kit. Wall mount and flat surface installation require separate accessory kits (TT.PR5MEC12 for surface mount, TT.PR5MEC11 for compact DIN rail, TT.PR5MEC00 for large DIN rail). A grounding screw is provided on the unit.

Q: Does the TSW304 include a power supply in the box?

No power supply is included. The standard package contains only the TSW304 switch and Quick Start Guide. Power supply units must be purchased separately, with options including screw terminal cables (TT.PR2FK20M), open wire cables (TT.PR2PL15B), barrel socket adapters (TT.PR2PD01B), and automotive 12/24V adapters (TT.PR2AM20M).

Reviews

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
