excom® remote I/O system - TURCK

excom® remote I/O system
Input module, analog, 4-channel
AI401Ex
The input module AI401Ex is used for the
connection of 2-wire transducers (active input = source mode / transducer passive) or 4wire 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 field circuits feature protection class Ex ia IIC resp. Ex iaD.
■
■
Input module for the connection of passive transmitters (active inputs) or active transmitters (passive inputs).
Complete galvanic isolation
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.

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. An additional impedance in the circuit is not necessary.
