The 1-channel IMXK12-AI01-1I-1I-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). 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

( 22 mA) in the

transducer circuit are output as current <

3.5 mA.

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 screw terminals.
