Industrial Fast Ethernet switch with fiber uplink

The PLANET ISW-511T is an unmanaged switch built for industrial networks. It provides four 10/100Base-TX RJ-45 ports with auto MDI/MDI-X and one 100Base-FX multi-mode fiber port. The fiber interface supports transmission up to 2 km over 50/125µm or 62.5/125µm cable at 1310 nm. A 2K MAC address table and 1MB buffer handle store-and-forward switching.

Suits harsh environments needing long

This unit fits DIN-rail or wall-mount installations and operates from -40 to 75 °C with 5–90 % non-condensing humidity. Redundant 12–48 V DC input with polarity-reverse protection keeps it running if one supply fails. It is not for networks that require Gigabit speeds, managed features such as VLANs or SNMP, or single-mode fiber distances beyond 2 km.

Four copper ports plus one multi-mode fiber port

The four RJ-45 ports comfortably handle 10/100 Mbps devices in factory automation, transportation or outdoor cabinets. The fiber uplink extends the segment to 2 km with a launch power of -14 to -20 dBm and receive sensitivity of -32 dBm. Bandwidth runs out when aggregate traffic exceeds the 100 Mbps line rate or when the 2K MAC table fills in very large flat networks.

Highlights

  • Industrial-grade operation from -40 to 75 °C
  • 2 km multi-mode fiber link for extended reach
  • Redundant 12–48 V DC input with reverse polarity protection
  • Unmanaged 4-port 10/100 RJ-45 plus 100FX uplink
  • DIN-rail or wall-mount format for flexible deployment

Questions about this item

What DC power source must I already have to run the ISW-511T?

You need a 12 to 48V DC supply; the switch accepts redundant inputs and includes polarity reverse protection.

Will my existing 10Base-T devices work on the four RJ-45 ports?

Yes — the ports support IEEE 802.3 10Base-T and 100Base-TX with auto MDI/MDI-X, so legacy 10 Mbps gear connects without crossover cables.

How can I verify the 100Base-FX link is operating correctly after installation?

Check that the FX port LED shows a solid link; the multi-mode fiber path supports up to 2 km at 1310 nm with receive sensitivity of -32 dBm.
