KI153, TB153, KB153 (wireless)

Description
The keyboard interface KI153 enables the operation
of input devices, like PC keyboards, trackballs etc.
within Ex- areas of Zone 1 and 2. For this, it offers the
possibility of converting several PS/2 or USB channels into intrinsically safe circuits which permit a signal transmission into Ex area.
A variety of input devices permits an adaptation to the
needs of different applications and places of work.
The EC- Type certificates of the KI153 as well as the
input components are matched and guarantee a prob-

lem-free interconnection of all components with a
system certificate from one hand. Verifications of intrinsic safety of all interconnections are provided, so
the user saves initialization of application specific
acceptance.
The KI153 also offers the possibility to use front-sided
input devices in pressurized enclosure housings (Exp) for which intrinsically safe controls are necessary.
(E.g. due to insufficient flushing of the contact areas
and/or insufficient impact strength)
