The 1-channel isolating transducer
IM33-14EX-CDRI is designed to operate intrinsically safe transmitters in the Ex area and
to transmit the measured signals to the nonEx area.
The device is equipped with an analog output of 0/4…20 mA; In addition, three relay outputs for limit values are available. The measured value can be viewed on a 2-line display.
A green LED indicates operational readiness,
3 yellow LEDs indicate the switching status of
the individual channels.

The measured value is permanently written to
a ring buffer with space for 8000 values. The
writing process is stopped with a predefined
trigger event, like for example "excess of limit
value". After that, the stored signal sequence
can be read out.
The device can be parametrized and configured via PC (FDT / DTM). For this, connect
the device to the PC via the 3.5 mm jack on
the front (the matching transmission cable
IM-PROG III can be ordered separately from
TURCK). In addition, a basic scope of parameters can be set via buttons and display
on the front as well as via the HART®
capable
power interface
