The 2-channel IMX12-AI01-2I-2IU-H0/24VDC

HART? isolating transducer is designed to operate intrinsically safe HART? 2-wire transducers in the Ex area and to transmit the measured signals to the non-Ex area.

In addition to the analog signal also digital

HART? communication signals can be transmitted bidirectionally. Furthermore, active and

passive 2-wire HART? transmitters can be

operated. The device is equipped with a 4

… 20 mA input and output circuit (either as

source or sink) or 1…5 V (source). The input

signals are transmitted in the range of 3.8…

20.5 mA without interference 1:1 and made

available at the outputs in the non-Ex area.

Wire-break ( 22

mA) in the transducer circuit are output as current < 3.5 mA or voltage < 0.875 V.

A green LED indicates operational readiness.

An error in the input circuit leads to a flashing

red LED according to NE44.

The device can be used in safety circuits up

to SIL2 (high and low demand according to

IEC 61508) and meets the requirements of

the NE21. It is equipped with removable screw

terminals.
