INTERFACE Cabling - System cabling and wiring interface

A wide range of automation devices are used for control processes. Whether it is just a small system with few I/O signals or a complex power station that is being put into operation, what they all have in common is that the signals from the automation device must be connected to the field level in an industrially compatible manner. INTERFACE Cabling offers two wiring variants, firstly the VARIOFACE system cabling and secondly the VARIOFACE wiring interface.

The VARIOFACE system cabling is a cabling concept that was specially developed for connecting to various automation devices. The system cabling comprises three harmonized components:

  1. Front Adapter
  2. System Cable
  3. Controller board

Quick, fault-free and uniform I/O wiring is possible with the aid of these three components. By selecting suitable modules, it is possible to realize various functions, such as a through connection, power amplification or signal conditioning.

VARIOFACE wiring interfaces are for universal use. Various interface modules with a 1:1 connection from a high-position plug connector to a different connection method are available. A rational connection to a control device with protection against reverse polarity can be realized with the aid of pre-assembled cables. A variety of potential distributors are available for splitting the control and operating voltage. Multi-channel relay / optocoupler modules can be used to adapt current and voltage signals between the field and automation level.

Fast and simple from the controller into the field - VARIOFACE
A large part of the costs incurred in automation systems today results from the cabling for the actuators and signaling units. On top of this, machines and systems are becoming more and more complex, which means that the cabling costs for the input and output stations are also steadily on the increase. In addition to cabling costs, the costs for planning, assembly, startup and documentation must be considered. The system concept of VARIOFACE system cabling reduces manufacturing costs through fast, faultless and uniform wiring of the input and output signals of a PLC. The system design comprises three components:
  • VARIOFACE front adapters
  • VARIOFACE system cables
  • VARIOFACE controller board



Wiring interface


The name VARIOFACE wiring interface covers a widely varied range of standardized interface modules; their connection principle and number of positions is fully tailored to the respective task in modern cabling technology. VARIOFACE modules are universal interface elements between the peripherals and the I/O level of automation devices for all areas of measurement, control and regulation systems, process engineering and control instrumentation systems. VARIOFACE modules simplify and optimize project planning, assembly and startup in all aspects of the system wiring. VARIOFACE modules provide both active and passive interfaces, or interfaces tailored to your individual requirements, for all fields of automation technology.
Fast and easy wiring



Advantages of VARIOFACE


VARIOFACE offers the user the following advantages:
  • Optimum adaption of the interface to the given cabling and connection requirements
  • Individual realization of adaptation functions such as electrical isolation, level matching, signal amplification
  • Simple and quick assembly on all common EN rails
  • Easy planning
  • Fast system startup and debugging thanks to clear cabling as well as clear identification of modules and positions
  • Saves space thanks to the high packing density of the compact modules
