ABB ContransIthe family with Instruction Manual for Freelance 2000
Chapter 1 - Glossary
ContransI- an interface programme with a wide functional spectrum beginswith signal matching
and ends with signal multiplication..
As the functionality ofprogrammable logic controllers and distributed controlsystems increase, so does the
requirement for electrical isolation, intrinsically safe isolation.
Contrans I drasticallyreduces the costs during project planing,commissioning and servicing,
compared with conventional signal processing components.
With this new systemconcept the electronic compartment (function module)and the junction box
(standard connectionbase) have been designedseparately.
During installation, wiring is connected using the standard basewhich is snapped onto the
DIN mounting rail.The function module is plugged into the prewired standardbase. The well arranged and
systematic terminal assignment helps to avoid wiring errors. Whenever servicing
is needed, the module is simply pulled out and the replacement plugged in.
It is not necessary to disconnect the wiring.
One error source is thereby eliminated. Special knowledge and tools are notrequired.
For the signal matching of I/O-boards of the distributed controlsystem Freelance 2000, 16 channel
backplanes which snap onto the DIN rail, have been designed.
The power supply is fed centrally and can be installed as an redundancy power supply.
The standard system cables with plugs on both ends makes it possible to plug the Contrans I
modules directly to I/O-boards.
Therefore :
wiring expense is brought down to a minimum, no engineeringof signal matching is required and
installation times are cut. Also the documentationeffort is drastically reduced.
Benefits :
For the using of Contrans I in combination to Freelance 2000 :
- Reduction of the Freelance I/O board variety (only four standard types are needed).
- Using Contrans I ascross wiring/fieldterminations.
