Ethernet extenders, PROFIBUS extenders, and serial extenders - easy network connection

Ethernet extenders, PROFIBUS extenders, and serial extenders – Easy network connection

With Ethernet extenders and fieldbus extenders, data can be transmitted over significantly greater distances (up to 20 km) than is customary via existing two-wire cables. This is necessary in particular if extensive systems are to be networked retrospectively and older cabling, such as telephone lines, is still in use. There is therefore no need to lay new cables.

Product List

Networked Unmanaged and Managed Ethernet extenders

Ethernet extender system

Ethernet extenders

Thanks to the Ethernet extenders, you can connect Ethernet networks across up to 20 kilometers via simple two-wire cables. By doing so, you can combine Managed and Unmanaged Ethernet extenders in one network. This innovative approach not only connects simple point-to-point Ethernet applications to create an extender system, but also wide-area IP networks. Furthermore, these devices enable extremely easy startup using Plug and Play and cost-effective networking and diagnostics of all devices and paths via IP: monitoring all of the extender paths and devices is easy, since only one Managed Extender is used. In the event of unexpected events such as line attenuation, you receive a detailed warning.

The Managed Ethernet extender makes your Ethernet network simple and cost-effective

Thanks to the Managed Ethernet extender, you can diagnose all devices and paths centrally via IP and forward messages automatically to the control center via SNMP (Simple Network Management Protocol).

New functions as of firmware v5.xx:

  • A VLAN (Virtual Local Area Network) can be used to virtually isolate critical IP networks and thus make them more secure.
  • The availability of the entire Ethernet network is guaranteed, even in the event of an emergency. This ensures that redundant network paths can be activated again via STP/RSTP (rapid spanning tree protocol) if required, for example, if a connection fails.
  • Eliminated system events on Unmanaged Ethernet extenders can now also be thoroughly diagnosed and an alert issued via SNMP forwarding.

The Managed Ethernet extender is available in two versions.

  • 4-port Ethernet switch with two DSL ports for point-to-point, line, and ring topologies and display
  • 1-port Ethernet switch with one DSL port for point-to-point applications and LEDs

Both devices have replaceable, high-quality surge protection with preventive function monitoring. This increases system availability.

Plug and Play also in ring structures

The Unmanaged Ethernet extender enables easy startup via Plug and Play. Unlike the Managed extender, the Unmanaged version is protocol transparent for the Ethernet network. The device does not have its own IP address. This means it can easily be used in any IP network without any prior network knowledge.

The Unmanaged Ethernet extender supports point-to-point, line, and ring topologies.

High-quality surge protection for Managed Ethernet extenders

PLUGTRAB PT-IQ surge protection for Managed Ethernet extenders

PLUGTRAB PT-IQ intelligent surge protection warns you before system protection is lost

PLUGTRAB PT-IQ is the forward-looking surge protection system from Phoenix Contact. Your advantage: multi-stage monitoring of protective devices. This means that failures can be foreseen. The special features of the protective devices include multi-stage signaling and remote signaling. These enable the following result messages to be sent via SNMP:

  • Performance limit reached, replacement recommended
  • Overloaded, replacement required

PROFIBUS extender

PROFIBUS extender for copper-based transmission up to 20 km

You can reach remote PROFIBUS devices via old copper conductors with a PROFIBUS extender. This enables data rates of up to 1.5 Mbps at distances of up to 1.5 km without a special cable. Two DSL ports per device enable the straightforward setup of redundant point-to-point or line structures.

In addition, mixed operation using copper conductors and fiber optics is also possible using a DIN rail connector.
Last but not least, power is supplied via USB cable, which enables device configuration without an external 24 V power supply.

Serial extenders

Serial extender – extend RS-232, RS-422 and RS-485 networks

The industrial serial extender enables a range increase beyond the serial standard for serial RS-232, RS-422 and RS-485 interfaces. This does not require a special cable. Any 2-wire cable can be used.

Point-to-point, line and star structures can be implemented using 2- and 4-wire cables. This means that networks can be implemented cost-effectively using the available in-house cables. Decommissioned phone lines or fieldbus cables that are no longer in use are ideal for this purpose.
