The Isolation-/Supply Unit LDX2 is a Exinput unit for non-Ex flow evaluation
units of Höntzsch. Therefore it is used
for measuring flow in hazardeous
areas.

For the Ex input of isolation-/supply
unit the following is valid:
the intrinsically safe circuit is conductively decoupled from both the power
supply and the output.

Installation note
The operation of the intrinsically safe
isolation-/supply unit LDX2 is only
permitted outside hazardous areas.

The isolation-/supply unit LDX2
supplies the intrinsically safe flow
sensor VA or FA and conductively
decouples the sensor signal from the
output signal.

Conformity to standards
The isolation-/supply unit LDX2 meets
the requirements of European
standards:
EN60079-0 Common standards
EN60079-11 Intrinsic safety
EN60079-26 Special requirements
category 1G

Installation in a CE approved
housing
As required, the isolation-/supply unit
LDX2 can be built into a CE approved
EMC housing along with a non-Ex
flow evaluation unit in LDG housing.
