The 1-channel IMX12-AI01-1I-2IUHPR/24VDC HART? isolating transducer with

splitter function is designed to operate intrinsically safe HART? 2-wire transducers in the

Ex zone and to transmit the measured signals

to the non-Ex zone. In addition to the analog

signals, the device also transmits the digital

HART? communication signals bidirectionally. The HART? signals are only transmitted

to output [A1]. Furthermore, active and passive 2-wire HART? transmitters can be operated. Connection is via removable screw terminals. 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 or voltage < 0.875 V. The

device can be powered from a power bridge

that also transmits a collective fault signal.

A green LED indicates operational readiness.

An error in the input circuit leads to a flashing

red LED 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.
