Copper Transmission 

Higher performance for your fieldbus networks. 

Features & Benefits 

  • Increase in performance due to a range increase and segmentation.
  • Use any two-wire lines to increase the range with the extenders.
  • Network extension due to signal processing with the repeaters.

Repeaters

The performance and availability of bus systems can be significantly increased by using repeaters. In addition to electrical isolation, bus segmentation with repeaters makes it possible to multiply the permissible coverage of the network and to extend the number of devices.

Terminator

The PSI-TERMINATOR-PB-T BUS active termination resistor ensures interference-free communication in PROFIBUS and RS-485 networks.

bbb-200x200

Interface isolator RS-232/RS-232

The RS-232 interface is an asymmetric voltage interface (common signal ground for all signals). As well as having a very low signal power, the signal ground is connected to ground potential. This results in very little immunity to interference and a maximum range of 15 m.

Extenders

Network PROFIBUS or serial devices that are up to 20 km away from each other via existing copper cables, e.g., using in-house telephone lines. Special Ethernet or fiber optic cables are not required.

Media Converters

Interference-free systems

Extreme EMC influences no longer present a problem. Thanks to fiber optic technology, you can achieve maximum interference immunity for practically any transmission system.

Features & Benefits 

  • Integrated optical diagnostics via bar graph display.
  • Early warning alarm issued in the event of a drop in transmission quality, with floating switch contact.
  • Use in potentially explosive areas approved for zone 2.
  • Modular station structure: automatic cross-wiring via DIN rail.
  • Maximum transmission distances with an extremely high data rate, thanks to fiber optic technology.

FO converters for PROFIBUS

The PSI-MOS-PROFIB/FO…devices convert copper-based PROFIBUS interfaces to fiber optics.

dddd-200x200

FO converters for DeviceNet™ and CANopen®

The PSI-MOS-DNET… fiber optic transmission system enables Device Net™and CANopen®users to benefit from simple and interference-free networking based on fiber optics. In addition, bus cable short circuits only affect the specific potential segment concerned. This increases overall availability, and improves flexibility when designing the bus topology. The use of fiber optic technology enables branch lines and star and tree structures to be created.

aaa-2-200x200

FO converters for RS-485 2-wire bus systems

The RS-485 2-wire interface is the most widely used interface in the field of automation technology. Well-known bus systems, such as SUCONET K, Modbus-ASCII, Modbus/RTU, S-BUS, and DH-485,are all based on this interface, as are many other company-specific bus systems.

bbb--200x200

FO converters for INTERBUS, RS-422,and RS-485 4-wire bus systems

The PSI-MOS-RS422/FO…devices are used for converting INTERBUS interfaces to fiber optics.

dddd-200x200

FO converters for RS-232 (V.24)

Due to its electrical properties, the RS-232 interface is very susceptible to electromagnetic interference and potential differences. For this reason, it can only be used for short distances of up to max. 15 m.

Fiber optic installation technology

Fiber optic data transmission in the industrial field has become increasingly important in recent years. In particularly critical applications with very high requirements regarding availability it has become standard. This is due to the many advantages that fiber optic data transmission has over traditional copper systems.
