The 2-channel IMX12-AI01-2I-2IUHPR/24VDC/CC 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 nonEx 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 signals are transmitted 1:1 without

interference in the range of 3.8…20.5 mA 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/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 NE21.

It is equipped with removable spring type terminals.

The device is equipped with removable

spring-type terminals.
