1.1 Function, configuration and mounting
Function
Ex-separator VEGATRENN 547 V Ex is used
for intrinsically safe, galvanically isolated
supply of up to two ultrasonic or radar
sensors. At the input side it is connected to
the two-wire-VBUS-line of the signal
conditioning instrument and provides at the
output side 2 x 2 ib-circuits. Each sensor is
supplied via two ib-circuits so that two
sensors can be connected to Ex-separator.
The Ex-separator can be used in conjunction
with the following signal conditioning
instruments or sensors:
- VEGAMET 514␣ V and 515␣ V
- EV-card of VEGALOG 571
- ultrasonic sensors VEGASON series 80
- radar sensors VEGAPULS series 64 and
series 80 for intrinscially safe supply “ib“.
The intrinsically safe ib-circuits are isolated as
well as from the not intrinsically safe circuits.
Configuration
Configuration
The Ex-separator VEGATRENN 547 V Ex is
designed in 19“-technology with 5 TE (= 25,4
mm). The connection is made via a multiple
plug acc. to DIN 41 612.
Mounting
There are the following mounting possibilities
- in housing type 506 with VEGAMET
- in carrier BGT 596 Ex with VEGAMET
- carrier BGT LOG 571 *) with VEGALOG
