Fieldbus distributors and segment couplers for PROFIBUS PA, PROFIBUS DP, and Fieldbus Foundation

Fieldbus distributors and segment couplers for PROFIBUS PA, PROFIBUS DP, and Fieldbus Foundation

Fieldbus distributors (also known as field device couplers) for PROFIBUS PA and FOUNDATION Fieldbus provide you with the option of extending your fieldbus in the field to suit your needs. The modular DP-PA coupler transparently connects PROFIBUS DP networks to PROFIBUS PA process networks in order to easily network your field devices with the control systems.

PROFIBUS DP/PA coupler

Modular PROFIBUS DP to PROFIBUS PA coupler

PROFIBUS DP/PA segment coupler

With the DP/PA coupler, you can transparently connect PROFIBUS DP networks to PROFIBUS PA process networks.

  • Up to 10 PROFIBUS DP or PROFIBUS PA modules per coupler for connecting up to four different DP/PA networks
  • Network redundancy with up to 10 modules
  • Integrated network diagnostics via communication interface module
  • Powerful, embedded web server for configuration and access to network diagnostics
  • Auto-detect any baud rate up to 12 Mbps transparently
  • System modules can be replaced during operation
  • Manage and configure PROFIBUS field devices using FDT/DTM

For each configuration, you require a head station for management, a PROFIBUS DP repeater, and a PROFIBUS PA module to interface with the PROFIBUS PA network. This modular approach allows configuration for specific applications. The preconfigured FB-HSB-DP/PA unit provides a basic package suitable for most applications.

Multi-channel FOUNDATION Fieldbus and PROFIBUS PA couplers for zone 2

The multi-channel field device couplers for PROFIBUS PA and FOUNDATION Fieldbus are designed for ambient temperatures of -50°C to +90°C. They are highly compact and connection takes place on one side from below in order to save even more space. This means you can optimally use your space and achieve maximum channel density in your distributor box.

The field device couplers have been registered by the Fieldbus Foundation.

Zone 1 fieldbus barrier for FOUNDATION Fieldbus and PROFIBUS PA

The multi-channel field device couplers for PROFIBUS PA and FOUNDATION Fieldbus are also called “fieldbus barriers” due to their Ex zone 1 approval.

  • Tested for ambient temperatures from -40°C to +80°C
  • Light and robust
  • Easy and space-saving installation with connection on one side from below
  • Registered by the Fieldbus Foundation

Intelligent circuits minimize contact bounce for high signal quality.
