The 1-channel IMX12-AI01-1I-1IU-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 signals, digital HART® communication signals can also be transmitted bidirectionally. Furthermore, active and passive 2-

wire HART® transmitters can be operated.

The device is equipped with an input circuit of

4…20 mA and an output circuit of 4…20 mA

(either as source or sink) or 1…5 V (source).

The input signal is transmitted 1:1 without interference in the range of 3.8…20.5 mA and

made available at the output 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 causes the red

LED to flash 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.
