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.

Stainless steel field junction box with 16 ports for use in hazardous locations. Includes 12-spur block device coupler (FB-12SP) for Foundation Fieldbus or PROFIBUS PA, trunk cable (+, -, S) is connected to a Plugtrab surge base (PT 4+F-BE).
PROFIBUS DP interface/repeater module
Modular PROFIBUS DP to PROFIBUS PA coupler
With the DP/PA coupler, you can transparently connect PROFIBUS DP networks to PROFIBUS PA process networks.
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.
Field device 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.
Fieldbus barrier for PROFIBUS PA and FOUNDATION Fieldbus
The multi-channel field device couplers for PROFIBUS PA and FOUNDATION Fieldbus are also called “fieldbus barriers” due to their Ex zone 1 approval.
Intelligent circuits minimize contact bounce for high signal quality.
Fieldbus distributor box
We provide a range of fieldbus distributor boxes specifically intended for the use of field device couplers. With approvals in accordance with ATEX, IECEx, and UL Class I, Division 2, they can be used with confidence around the world.
The pre-assembled boxes come in two versions with and without surge protection for the trunk line. They connect the trunk line to the field devices.
