IM12-AI01-1I-1IU-H0/24VDC中文资料图尔克数据手册PDF规格书

The isolating transducers IM12-AI01-1I-1IUH0/24VDC 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 4…20 mA output circuit (either

as source or sink) or 1…5 V (source). The input signals are transmitted 1:1 without interference within a range of 3.8…20.5 mA. In addition, digital signals can also be transmitted

bidirectionally in accordance with the HART®

protocol. 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.
