Intrinsically safe signal connections (option)

3.7.1

Technical design

When the GMS841 (ATEX/ IECEx) is used in Ex zones, the analog outputs, digital inputs and 
outputs have to be realized as intrinsically safe signal connections when the signals are 
used in an Ex zone. 

Additional modules are fitted for this purpose (safety barriers). All intrinsically safe 
connections are configured according to customer requirements.

Technical information on intrinsically safe signal connections and switching, see 
delivered Operating Instructions of the safety barriers.
