The 2-channel IM12-AO01-2I-2I-HPR/24VDC

signal isolator is designed to transmit the normalized current signal galvanically isolated

1:1. 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. 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. An error 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.

The device is equipped with removable screw

terminals.
