The 2-channel IMX12-AO01-2I-2IHPR/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 and the

common alarm output switches to conductive. 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 can be powered from a

power bridge that also transmits a collective

fault signal.

The device is equipped with removable

spring-type terminals.
