The 2-channel IMX12-AO01-2I-2IHPR/24VDC 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 also digital HART® communication signals can

be transmitted bidirectionally. Typical applications are for example, the control of I/P converters or indicators in the Ex area. The device can be powered from a power bridge that

also transmits a collective fault signal.

The Pwr LED lights green to indicate 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. A fault 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. It is equipped with removable screw

terminals.
