The 1-channel IM12-AO01-1I-1I-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 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

the NE21. It is equipped with removable screw

terminals. The device can be powered from a

power bridge that also transmits a collective

fault signal.

The device is equipped with removable screw

terminals.
