RF540 and RF541 are subracks for assembly of auxiliary equipment like modems and certain
connection units for communication links.
RF541, the 19-inch variant is described below. RF540 for 24-inch standard differs in width and
number of units only.
A maximum of nine modems, for example, type TC625 or TC630 for Advant Fieldbus 100,
can be fixed by two screws included in the modem design. (RF540 12 modems.)
As an alternative, a top hat rail is available for flexible application.
The subrack provides two contact groups which simplify 24 V distribution from the cabinet
supply to the units.
The pluggable connection of the power supply implies increased maintainability.
