M34-14EX-CDRI中文资料图尔克数据手册PDF规格书

The 1-channel Ex-area temperature measuring amplifier IM34-14Ex-CDRi is designed to

evaluate the temperature-dependent changes

of Ni100/Pt100 RTDs and thermocouples

types B, E, J, K, L, N, R, S, T and to output

them as temperature-linear current signals

0/4…20 mA. Furthermore, resistors, potentiometers or low voltages can be mapped linearly as current signals in a range between

-160…+160 mV.

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.

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 limit value exceeded. 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

The signals are transformed according to ITS

90/IEC 584 for thermocouples and according

to IEC 751 for Pt100 RTDs and provided temperature linear at the current output.

Cold junction compensation of thermocouples

is either realized via an externally connected

Pt100/Ni100 resistor, via temperature measured inside the amplifier or via an individually

adjustable constant temperature value.
