The input module AI401Ex is used for the

connection of 2-wire transducers (active input = source mode / transducer passive) or 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 the excom system. The field circuits feature ignition protection type Ex ia IIC resp. Ex

iaD.

The field circuits are galvanically isolated from

each other.

HART-compatible transducers can be connected to the module. The field device can

thus be parametrized directly at the terminals

on the DIN rail with a licensed modem. Additional impedance in the circuit is not necessary.

The measuring range is digitized in the scope

of 0…21 mA. For clear reading, the digitized

value is displayed in a range of 0 … 21000

(independent of the parametrized measuring

range) and transmitted to the host system.
