The isolating transducers IM12-AI01-1I-2IUH0/24VDC transmit analog measured signals

galvanically isolated. The devices are suitable

for operation in zone 2.

The 1-channel device has one input for the

operation of HART? 2-wire transducers as

well as active and passive HART? 2-wire

transmitters. Connection is via removable

screw terminals.

The device is equipped with a 4…20 mA input circuit and two 4…20 mA output circuits

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

The input signal at input [I1] is transferred 1:1

to outputs [O1] and [O2] within a range of 3.8

mA…20.5 mA without interference (splitter operation). In addition, digital signals can also be

transmitted bidirectionally in accordance with

the HART? protocol. Digital HART? signals

are only transmitted to output [A1].

Wire-break (

22 mA) in the transducer circuit are output as

current < 3.5 mA/voltage < 0.875 V.

The devices have a green power LED (Pwr).

For each input circuit there is a red status

LED. 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.

The device is equipped with removable screw

terminals.
