Supply Module for Hand-held Scanner for ATEX Zone 1 and 21

Features
■ No external isolators required
■ Direct mounting in ATEX Zone 1 and 21

Description
The supply module ensures an intrinsically safe
supply and it isolates the data line for the BCS 160ex.
Two variants of the supply module are available for
the hazardous (potentially explosive) area:
- AC 100 V to AC 250 V
- DC 24 V
All variants are equipped with an RS232/RS422
interface or USB interface.
In the hazardous areas of Zone 1 and 21, the supply
module is joined to the hand-held scanner by
means of a plug-in connection.
