Media Converters

Media converters connect various transfer media, such as copper cables and fibre-optic cables. Fibre-optic cables are capable of transferring data over distances of several kilometres and reduce the failure susceptibility in EMC-critical environments.

Serial Media Converters

In industrial environments, data is still transmitted via serial interfaces (RS-232/485). If the achievable cable lengths of about 10-15m (RS-232) or up to 1000m (RS-485) are not sufficient when using copper cables, fibre optic cables (LWL) are used. This allows distances of several kilometres to be bridged when using media converters in pairs.

Ethernet Media Converters

With Ethernet media converters, a network can be built using fibre optic cables instead of copper cables. This has 2 advantages: a) the maximum Ethernet cable length is increased from 100m to 2km or more and b) the transmission lines are immune to EMC interference.

CANbus Media Converters

With CANbus media converters, a CANbus network can be routed via fibre optic cables instead of copper cables. The most common reason for using fibre optics instead of copper is to avoid EMC and similar electrical interference on the CANbus lines, which is not uncommon with "heavy equipment".

PROFIBUS fibre optic converters

PROFIBUS fibre optic converters are used to transmit PROFIBUS signals via fibre optic cables instead of copper cables. They are particularly suitable for use in EMC-critical environments.

EtherCAT fibre optic converters

EtherCAT fibre optic converters enable EtherCAT connections to be established via fibre optic cables instead of copper cables.

RS-485 Converters 

RS-485 interface converters convert from RS-485 to RS-232, either as pure protocol converters from Modbus TCP to Modbus RTU, or as RS-485 bus masters, allowing communication with multiple RS-232 devices per assigned RS-485 address. A typical scenario is the communication of a host PC with several RS-232 laboratory balances or the addressing of several RS-232 frequency converters via a host PLC. 

RS-232 Converters

RS-232 interface converters give a downstream RS-232 device an RS-485 interface. Compared to RS-232, this has the advantage of a long maximum distance of up to 1000m, insensitivity to electrical interference and cost-effective installation via twisted-pair telephone cable. The converters are suitable for DIN rail or wall mounting. The models offer different types of insulation.

USB Converters

USB interface converters enable the connection of serial devices via the USB interface. When the converter is plugged into the USB port, the Windows OS creates a virtual COM port via plug'n'play, through which the software communication takes place. The converters are suitable for DIN rail or wall mounting. Particularly useful and indispensable in any service case are the small transducer plugs or cables that plug directly into the USB port of the PC.

Signal conditioning modules

Signal conditioning modules adapt the electrical levels of sensors/actuators to the specified signal levels of I/O modules, PLCs or controllers. Typical applications are the conversion of 4-20 mA or millivolt (DMS) signals to standardised 0-10 volt levels or e.g. galvanic isolation (3000 VDC) between I/O signal and expensive host controller.
