Media
Converters in industrial design |
 |
| |
|
|

In
addition to being deployed in local networks, Ethernet
is spreading increasingly across production
environments. Modern machine control systems and
industrial plants are already equipped with
10/100Base-TX interfaces.
|
| |
|
Production
environments can also benefit from flexible
media conversion by employing fiber optics as
they are insensitive against electromagnetic
interference and do not suffer from galvanic
separation, enable longer transmission
distances, and are highly reliable. However,
deployment of fiber optics for such as active
hubs, switches, and media converters in office
environments is fundamentally different from the
deployment in production environments where fast
initialisation, high robustness and
availability, as well as fail safe operation are
required. For this extremely demanding
environment, we have developed special media
converters in industrial designs. |
|
| |
|
The
existing product range of Ethernet (10Base-FL/10Base-T)
and Fast Ethernet (100Base-FX/100Base-TX) media
converters has been complemented with new media
converters for serial interfaces in production
environments and RS-232/V.24, RS-422/V.11 and RS-485
copper/fibre optics converters. An integrated mounting
device allows the direct installation on 35mm hat rails. |
| |
|
The
components are driven by a 24V DC power supply. A second
mains terminal can be used for redundant power supply.
The Ethernet converters have a switch for reversing the
port input of the RJ-45 connector. Therefore, the
100Base-TX copper connection can be carried out via
common 1:1 patch cables. In addition to the SUBD-9
connection, the serial converters also have parallel
terminals for flexible bus installation. Floating
contacts are another option. Messaging systems can be
connected via special terminals in order to indicate
connection failures and trigger certain actions. |
| |
|
The
fibre optic connector is located on the underside of the
device. This ensures protection of the optical
transceiver against dust and contamination. |

RS-232/422/485
industrial media converter
For connection with standarised serial interfaces offers special
fiber converters in industrial design. There are special
converter for RS-232, RS-422 and RS-485 available.
|
|
|
|
|
| The
RS-485 converter is compatible to the different field
bus system such as profibus, bitbus and interbus. The
conversion is done transparent, so there is no adaption
to the data rate necessary. |
| The
design allows the direct mounting on 35 mm hat rails.
The power supply of the devices is done with a 24 V DC
connector. A second input if for the connection of a
second redundant power supply is included. |
|
|
|
|
For
a flexible bus installation the converter has beside the
standard SUBD-9 connector a parallel screw connector. Ti the
potential free contacts it is possible to connect external alarm
systems, which can generate specific actions in case of failure.
