  • State-of-the-art: with proven Phoenix Contact reliability and innovation

Redundant fieldbus power supply

Reliable field power supplies with ACB Technology  

Reliable field power supplies with ACB Technology

Reliably supply your FOUNDATION Fieldbus loops with redundant single- or four-channel power supplies. The devices can be plugged in, which means they can be replaced quickly and flexibly. Furthermore, the ACB Technology (Auto Current Balancing) ensures a considerably higher device service life and maximum reliability for your process application thanks to symmetrical loading of the power supplies.

The integrated diagnostics function and relay outputs ensure permanent monitoring.

Your advantages:

  • Modular structure for increased system availability
  • Integrated diagnostic function with relay output
  • Maximum service life, thanks to ACB (Auto Current Balancing) technology
  • Compatible with Yokogawa, Invensys, and universal D-SUB-25 solutions

Modular fieldbus coupler range for FOUNDATION Fieldbus

Modular fieldbus coupler range for FOUNDATION Fieldbus  

Fieldbus coupler: flexibility and modularity in a single range

The modular FOUNDATION Fieldbus device coupler system consists of three main devices: the trunk line module, coupler modules, and, when required, a diagnostics module. The trunk line module forms a new fieldbus station. The module offers numerous shielding options and an integrated termination resistor.

The fieldbus device couplers with one or two outputs are short-circuit-proof, thereby protecting your network. The supply voltage for the modular system is sub-distributed via a connector which is simply snapped onto the DIN rail.

For Zone 2 installations, with connection of Zone 0, 1, and 2 instruments in the same housing, the FB-MODULAR partition plate is available for implementing intrinsically safe wiring clearances.

The field diagnostics module is available in two versions. One version works with the modular DIN rail connector and therefore saves on complex cabling. The other is fitted with connection terminal blocks via which device couplers from other manufacturers can be connected.

Integration in the control level is via standard H1 communication and device management using DD (Device Description), EDDL (Electronic Device Description Language), and DTM (Device Type Manager).

Fieldbus couplers with 6 and 12 channels

Fieldbus couplers with 6 and 12 channels  

Local diagnostics and space-saving cabling

The multi-channel fieldbus device couplers 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 use your space as effectively as possible and achieve maximum channel density in your distributor box.

The termination resistor is integrated into the device.

The fieldbus couplers have been registered by the Fieldbus Foundation.

Zone 1 fieldbus barrier with 8 or 12 channels

Zone 1 fieldbus barrier with 8 or 12 channels  

The lightest Zone 1 fieldbus barriers in the industry

The new fieldbus barriers are device couplers that are specially approved for Zone 1. They have been tested at ambient temperatures of -40°C to +80°C and are thus suitable for any process application.

The fieldbus couplers have been registered by the Fieldbus Foundation.

Fieldbus distributor boxes with fieldbus couplers and system approval

Fieldbus distributor boxes with fieldbus couplers and system approval  

Turn-key distributor solution for installations around the world

Specified for global use and internationally approved, these distributor boxes make life much easier for process engineers. Thanks to ATEX, IECEx, and UL Class I, Division 2 approvals, they can be used with confidence around the world.

The pre-mounted boxes come in two versions with and without surge protection for the trunk line. They connect the trunk line to the field devices.

  • Ready-to-use distributor boxes made from brushed 316L stainless steel
  • Available with 10 or 16 ports
  • Quick and easy mounting with Zone 2 block fieldbus couplers
  • Little space required and low weight
