The 1-channel Ex-area temperature measuring amplifier IM34-12EX-CRI is designed to

evaluate the temperature-dependent changes

of Ni100/Pt100 RTDs, thermocouples types B,

E, J, K, L, N, R, S and T or low voltages in a

range of -160…+160 mV and to output them

as temperature-linear current signals 0/4…20

mA.

Alternatively, Ni100/Pt100 RTDs in 2, 3 or 4-

wire technology can also be operated at the

input circuit of the measuring amplifier. The

Ni100/Pt100 input can either be used as external cold junction compensation for the thermocouple or as independent measuring input.

The device has an additional relay output to

monitor over or undershoot of a limit value.

With the software tool Device Type Manager

(DTM), the device can be configured and parameterised via PC. 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).

The following settings are available:

■ Connection mode (2, 3 and 4-wire technology)

■ Measuring range, start

■ Measuring range, end

■ Limit value

■ Input circuit monitoring for wire-break

■ Behaviour of the current output in case of

errors in the input circuit: 0 or > 22 mA

■ Internal or external cold junction compensation

■ Output current (0/4…20 mA)

■ Temperature (°C or °K)

■ Mode (resistor, thermocouple, low voltage,

line compensation)

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.

■ Input for Pt100/ Ni100 resistors, thermocouples and millivolt signals in 2, 3 or 4-

wire technology

■ Output circuit: 0/4…20 mA, limit value relay

■ Parameterized via PC (FDT / DTM)

■ Complete galvanic isolation

■ Input reverse-polarity protected

■ ATEX, IECEx, CFMUS, UL, TR CU, INMETRO

■ Installation in zone 2
