Hirschmann RH1-TP Description And Operating Instructions

Description and Operating Instructions
ETHERNET Twisted Pair Industrial
Hubs for ISO/DIN Rail

The rail hub RH1-TP supports a fast and rea­sonable network expansion. You can
connect up to four data terminal equip­ments or further twisted pair segments via
twisted pair.

For startup procedure just fit the rail hub
on an ISO/DIN rail, without any further con­figuration time. The V.24 voltage is supplied
via the terminal block and can be feed in
redundantly.

The terminal block contains an integrated
indicator contact, receiving error and war­ning messages of the rail hub which are
defined as digital signals. These signals e.g.
can be utilized as process messages by a
programmable logic control (PLC). The indi­cator contact becomes active as soon as
disturbances appear in the rail hubs, that is
when a power supply should fail or at least
one TP port reports a faulty link status or
has auto partitioned.

For diagnosis there are LEDs available
which indicate collisions, link status, seg­mentation, power and received data.

The railhub has four twisted pair (TP)
interfaces. It is possible to connect up to
four terminals or other TP segments using
TPs.

The module conforms to the specifications
of ISO/IEC standard 8802-3.

You will find a detailed description for con­struction of a local area network on network
planning and installation in the “Ethernet
manual“ (Order no. 943 320-011).
