Long specification

Ex isolating switch amplifiers for Namur sensors, 2 channels
2-channel isolating switch amplifiers in 22.5 mm width with an external power supply,
to transmit and isolate Namur sensor signals from Ex zones 0,1, 2 into the safe
zone.
On the output side there is a potential-free relay contact per channel with closing function
and a common alarm contact ("a" contact) for status/error messages.
The component can be configured using standard FDT/DTM software.
