The 1-channel IMXK12-AO01-1I-1IH0/24VDC/CC signal isolator is designed to

transmit the normalized current signal galvanically isolated 1:1 from the non-Ex area to the

Ex-area. In addition to the analog signal, digital HART® communication signals can also be

transmitted bidirectionally. Typical applications

are for example the control of I/P converters

or indicators in the Ex area.

The green LED indicates operational readiness. The device can detect a wire break or

short circuit on the field side, the input then

switches to a high impedance state. 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.
