The input module AI41Ex is used for the connection of 4-wire transducers (passive input =
sink mode / transducer active).
The module features protection class Ex ib IIC
and can be mounted in zone 1 in combination
with excom. The ignition protection type of the
inputs is Ex ia IIC.

The inputs are galvanically isolated from each
other.
The resolution is 14 bit, i.e. the analog value
between 0…21 mA is represented as a number between 0 and 16383. For clear reading,
the digitized value is displayed in a range of 0
… 21000 and transmitted to the host system.
For transmission to the host system, voltage
is indicated as a value in a range between 0…
10000.
