for hand-held scanner for ATEX Zone 1 and Zone 21

Description

The power pack ensures an intrinsically safe

supply and isolation of the data line for the

BCS 3800

ex

hand-held scanner.

In the Ex area each power pack is available in

three variants:

- AC 100 V up to 250 V

- DC 24 V

- DC 12 V

Both variants are supplied with RS232 and RS422

interface.

In the Ex area in Zones 1 and 21 the power pack

is connected to the BCS 3800

ex

hand-held

scanner by means of a plug-in connection.
