Unmanaged switch PLANET ISW-511T

The PLANET ISW-511T is an unmanaged industrial Fast Ethernet switch designed for operation in wide-temperature environments. It provides four 10/100Base-TX auto-negotiation RJ-45 ports and one 100Base-FX multi-mode SC fiber port for up to 2 km transmission. Built for durability, the ISW-511T offers immunity to electromagnetic interference and protection against electrical surges commonly found in transportation, manufacturing and traffic-control cabinets. The compact metal case supports DIN-rail or panel mounting and accepts a wide DC input range with dual-redundant, reversible-polarity 12–48 V DC power inputs for higher availability.

Advantages

The ISW-511T operates reliably across a wide temperature range (-40 to 75 °C) and is tolerant of harsh industrial conditions. It combines copper and fiber interfaces for flexible network deployment, supports basic L2 switching with a 2048-entry MAC table and 1 Gbit/s switching capacity, and is simple to install thanks to its compact form factor and multiple mounting options. Integrated wide-range DC power inputs and redundant power capability increase operational uptime.

Suitable for

• Transportation network equipment (roadside cabinets, vehicle networks)
• Factory automation and plant-floor networks
• Security and surveillance systems in outdoor or unheated locations
• Small industrial LAN segments requiring fiber uplink for extended distance

How to use

Install the ISW-511T on a DIN rail or panel inside the equipment cabinet and connect the DC power inputs, observing polarity if not using the reversible feature. Connect copper Ethernet devices to the RJ-45 ports and the fiber uplink to the SC multi-mode port for extended distance links. The switch is plug-and-play and requires no configuration; it performs auto-negotiation on copper ports and forwards frames based on its MAC address table.

Recommendations

Place the switch in a ventilated enclosure and use appropriate surge protection on long external cables. Choose multi-mode fiber for distances up to 2 km and verify that connected devices support the same duplex and speed settings for optimal performance.
