The 1-channel IMX12-AI01-1I-1IUHPR/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 can be powered from

a power bridge that also transmits a collective

fault signal.

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.
