The 1-channel IMX12-AI01-1I-2IU-H0/24VDC

HART? isolating transducer with splitter function is designed to operate intrinsically safe

HART? 2-wire transducers in the Ex zone

and to transmit the measured signals to the

non-Ex zone. In addition to the analog signals,

the device also transmits the digital HART?

communication signals bidirectionally. The

HART? signals are only transmitted to output

[A1]. 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 (< 3.5

mA) and short-circuit (> 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.
