The 1-channel IMX12-AI01-1I-2IUHPR/24VDC/CC HART® isolating transducer

with splitter function 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, the device also transmits the digital HART® communication signals bidirectionally. The HART® signals are only transmitted

to output [O1]. 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.
