Fieldbus repeaters - for PROFIBUS and RS-485 bus systems

Fieldbus repeaters – For PROFIBUS and RS-485 bus systems

Using fieldbus repeaters for PROFIBUS and RS-485 bus systems, you can extend your network over a wide area regardless of the data rate. Even the number of devices can be extended by segmenting with repeaters. You can increase the range, transmit with reliable EMC, and extend and distribute channels as required. The modular concept supports any combination of copper and fiber optic channels.

Modular design

Copper repeaters for increased system power:

  • Start delimiter detection filters damaged PROFIBUS telegrams
  • Through the bit retiming, the devices can be cascaded as deeply as necessary
  • High-grade electrical isolation ensures immunity that is suitable for industrial applications

The modular concept of the PSI-MOS devices also guarantees the desired mix of copper and fiber-optic channels can be achieved: the devices can be quickly and easily connected to each other via the DIN rail connector. As such, this is how the cross-wiring for data signals and supply voltage is achieved.

  • Fast installation without wiring errors
  • Combine up to 10 devices to suit the application and extend to up to 30 channels, either in copper or FO
  • Even during operation, individual modules can be replaced without affecting the others
  • Optional system power supply can also be used redundantly
Fieldbus repeaters – extension through segmentation

Fieldbus repeaters – extension through segmentation

Using Phoenix Contact repeaters, you can extend your network over a wide area regardless of the data rate. Even the number of devices can be extended by segmenting with repeaters. You can increase the range, transmit with reliable EMC, and extend and distribute channels as required. The modular concept supports any combination of copper and fiber optic channels.

  • With integrated bit retiming with signal processing, the repeaters can be cascaded to any required depth
  • The integrated bit oversampling ensures interference-immune telegrams
  • Start delimiter detection detects damaged PROFIBUS telegrams without causing any impacts and filters them out of the network
Active termination for PROFIBUS and RS-485 networks

Active termination with PSI-TERMINATOR-PB-TBUS

Active termination for PROFIBUS and RS-485 networks

Actively terminate PROFIBUS and RS-485 networks with ease using the PSI-TERMINATOR-PB-TBUS.

This gives you important advantages:

  • Interference-immune bus communication through permanent, active termination: you can connect and disconnect bus devices during operation
  • Fixed programming interface on the network
  • Redundant power supply
  • Supply voltage routed through a DIN rail connector for use in combination with other devices

You use the D-SUB connection to supply active programming and diagnostics devices with power. You can also use the device as a defined service interface within a bus system.
