Fast and error-free signal connection with the Termination Carriers for MACX Analog Ex

The consistent interface solution for system technology

Termination carriers with MACX Analog Ex signal conditioners  

MACX Analog Ex termination carriers with standard DIN rail devices

Termination carriers are compact solutions for quickly and smoothly connecting DIN rail devices from the MACX Analog Ex series to input and output cards of automation systems.

Connect the termination carriers to your controller quickly and smoothly using pre-assembled VARIOFACE system cabling – Plug and Play.

You can therefore combine the advantages of modular DIN rail devices with those offered by plug and play system cabling to create a consistent solution for system technology.

Compact – for high packing density

80 x 200 cm control cabinet fitted with MACX Analog Ex termination carriers  

Up to 384 channels in an 80 x 200 cm control cabinet

Save up to 30% space compared to other solutions on the market:

  • Compact design: with a height of 160 mm and a depth of 170 mm.
  • Space-saving arrangement of system connections: the radius of the system cables does not protrude beyond the modules.
  • DIN rail bracket with integrated end clamp, enabling several termination carriers to be mounted side by side.

With the termination carrier, you can install up to 384 channels in an 80 x 200 cm control cabinet – when using 2-channel MACX Analog Ex devices.

Robust – for high system availability

Modular power concept for high availability

The termination carrier is particularly robust:

  • Stable vibration-resistant aluminum profile
  • Integrated DIN rail contour, enabling modules to be fixed securely
  • PCB protected in the profile - mechanically decoupled

Modular power concept

The signal conditioners are connected to a separate power and error message module via integrated DIN rail connectors.

As such, the PCB is terminated in a passive manner – it does not contain any active components whose failure would require the termination carrier to be replaced.

The separate power and error message module offers additional advantages:

  • Simple or diode-decoupled redundant supply
  • Error message in the event of auxiliary voltage failure, fuse fault, and line fault
  • Replaceable fuses

Easy maintenance – for simplified documentation and startup

Termination carrier with hot-swappable module replacement  

Module replacement during operation – hot-swappable

Only standard DIN rail devices are used on the termination carrier, special devices are not required.

This makes the termination carrier particularly easy to maintain:

  • Only one engineering design for DIN rails and system applications
  • Quick and safe connection to the termination carrier PCB with plug-in and coded cable sets
  • Control-side connection to the front adapter via pre-assembled system cables
  • Easy-access system connections and module connection terminal blocks
  • Module replacement during operation – hot-swappable

Flexible – for optimum adaptation

Profile sections without pitch markings  

Profile sections without pitch markings for controller-specific number of channels

In addition to the universal termination carriers with 1:1 pinning and optional HART signal decoupling, other control-system-specific versions are available, are being planned or can be implemented by us in accordance with your specifications.

  • Profile sections without pitch markings for controller-specific number of I/Os
  • Can be specifically and optimally adapted for I/O cards of various automation systems with different system plugs and front adapters.

Professional system cabling

System cables connect the termination carrier to the automation system  

Fast connection to controller-specific I/O cards

The universal termination carriers can be used to connect up to 16 MACX Analog Ex signal conditioners to the input and output cards of automation systems.

Connect the termination carriers to your controller using pre-assembled VARIOFACE system cabling – quickly and smoothly.

The cables have high-position numbers of channels and both standardized and controller-specific connections, e.g., for:

  • ABB
  • Emerson
  • Honeywell
  • Invensys
  • Siemens
  • Yokogawa
  • Further individual solutions

Application example: diagram of a typical system with point-to-point wiring

Many process technology systems have areas where potentially explosive atmospheres may occur. As such, measuring and control circuits are designed with intrinsic safety protection type Ex i.

MACX Analog Ex i signal conditioners and measuring transducers isolate intrinsically safe circuits from non-intrinsically safe circuits at interface level. They safely limit the energy supplied to the Ex area and also perform extensive tasks for signal conditioning.

Termination carriers and system cables significantly reduce wiring effort between the interface level and the process control level

Fast installation and startup with plug and play system cables

In the Ex area, cables from intrinsically safe field devices are grouped together via distribution boxes to form multi-strand master cables. In the non-Ex area, they are then routed to the interface level via marshalling panels. From here the signal conditioners are individually wired to the relevant I/O cards.

The significant amount of time needed for installation and startup is greatly reduced by the termination carrier – thanks to the use of plug and play system cables.
