3.2 Analog Signal Transmitter IM35-22Ex-Hi/24VDC

The two-channel data transmitter IM35-22Ex-Hi/24VDC is designed to transfer standard
galvanically isolated current signals from the safe area to the explosion hazardous area in a 1:1
transmission mode.
In addition to the analogue signal, digital HART® communication signals can be transferred
bidirectional.
Typical applications are the control of I/P converters (e.g. at control valves / actuators) or of
indicator displays in explosion hazardous areas.

The Analog Signal Transmitters IM35-22Ex-Hi/24VDC are considered to be Type A
components with a hardware fault tolerance of 0.
The description above is valid for all versions of the analog signal transmitter with the exception
that this version has two input and two output channels. The differences between the versions
are described in Table 1.
