The intrinsically safe circuits are reliably (galvanically) separated from the non-intrinsically
safe circuits up to a peak value of the nominal voltage of 375 V.
On instruments with 2 channels (VEGATOR 527 Ex) the intrinsically safe circuits are reliably
separated.
CE conformity
VEGATOR 521 Ex, 522 Ex, 523 Ex and 527 Ex signal conditioning instruments meet the
protective regulations of EMC (89/336/EW) and NSR (73/23/EWG). Conformity has been
judged acc. to the following standards:
EMC
Emission EN 50 081 - 1: 1993
Susceptibility EN 50 082 - 2: 1995
NSR EN 61 010 - 1: 1993
