Modular fieldbus components from Phoenix Contact can be used to extend your system according to your requirements or to replace individual modules quickly. This means that you can reduce the cabinet area and eliminate costs for unused capacity. Combined with redundant DC power supply units, surge protection, and connecting cables, Phoenix Contact offers a complete system architecture.

Your advantages

  • Everything from a single source: a complete system architecture is available
  • Tailored installation, thanks to the modular structure
  • High level of safety: approved for potentially explosive areas up to zone 0

Diagnostics for FOUNDATION Fieldbus in the field

Field diagnostics modules  

Diagnostic accuracy from remote locations

The field diagnostics module (FDM) can be used to check the signal quality of the fieldbus directly in the field in environments that are potentially susceptible to interference. The diagnostics enable preventive measures to be taken to ensure optimum device availability and prevent the sudden loss of communication between the devices.

The field diagnostics module is available in two versions. One version works with the modular TBUS system 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).

Due to use in the field, the measurements are not affected by long cable paths. The data is transmitted back to the control room in realtime, where it can be evaluated directly by the system operator. This means that no maintenance authorizations or process interruptions are required.

Compact fieldbus junction boxes with device couplers

Device couplers can be used to connect the process controller to your field devices. The pre-installed external termination resistor helps to avoid errors during startup.

The low design width of the fieldbus junction boxes reduces the size and weight of the control box.

This provides important advantages for you:

  • Single-point integrity: one coupler module per field device for increased system availability
  • Modular device couplers for flexible system expansion
  • Optimized maintenance, thanks to fast module replacement during operation
  • Quick and easy installation of prewired fieldbus junction boxes
  • Space saving, thanks to its optimal size and weight

Redundant power supply unit

Redundant power supply unit with ACB technology  

Redundant power supply unit with ACB technology

Protect your system against unplanned downtime with a redundant power supply unit. It supplies power to a segment with several devices and offers maximum reliability for process applications. 

This provides important advantages for you:

  • Modular structure for increased system availability
  • Integrated diagnostic function with relay output
  • Maximum service life, thanks to ACB (Auto Current Balancing) technology
