Ex-Separator Module iXT0 - rev. 02 / 28.08.2017

page 21

11 Functional descriptions

The iXT0 is an intelligent electronic separation interface which is used between
non Ex-area and Ex-zone 1.
The iXT0 is conceived for correct Ex-technical separation of the following sensors:

NIVUS velocity sensors:

−

POA-V2

−

CS2

−

EBM-Box (Electronic box Mini)

−

OFR-EV

NIVUS level sensors:

−

OCL-L1

−

i-series sensor

−

NivuCompact

−

NivuBar

The iXT0 intrinsically safe supplies the sensors mentioned above with power and
ensure reliable data transmission between sensors and the NivuFlow xxx transmit-
ter within the limits of its technical specifications.
The iXT0 draws its required power from the transmitter.
