Edition • 2023-07-21T16:28:01+02:00 The 1-channel temperature measuring am- plifier IM34-11Ex-CI/K60 is designed to eval- uate the temperature-dependent changes of Ni100/Pt100 (RTD), thermocouples (TC) 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 of 0/4… 20 mA. Alternatively, RTDs in 2, 3 or 4-wire technology can be operated at the input circuit of the measuring amplifier. The Ni100/Pt100 input can either be used as external cold junc- tion compensation for the thermocouple or as independent measuring input. If the thermocouple leads are led up to a tem- perature measurement amplifier, we recom- mend to use the cold junction compensation module IN IM 3-CJT from TURCK (ident-No.: 6900524). This way the maximum possible accuracy is achieved. In order to increase the measurement speed with fast temperature changes on thermocouples, the device switch- es into the "Fast Mode" after 200 ms at the very latest after a gradient of 200 µV/s has been exceeded. Thereafter the cycle time of the thermal voltage measurement is < 80 ms. This means that no wire-break monitoring and no measurement of the cold junction tempera- ture will occur. After the gradient drops below 80 µV/s the device will switch back to "Normal Mode“.

NOTE: The temperature gradients in the table are only approximate values for defined tem- perature ranges. For the precise determina- tion of the temperature gradient the character- istic of the sensor in question and the associ- ated operating point must be included. The devices are parametrized and configured via PC with the software tool "Device Type Manager" (DTM). For this, connect the tem- perature measuring amplifier to the PC with the 3.5 mm jack plug on the front. The ready- made transmission cable can be ordered from TURCK under the type name IM-PROG (ident no. 6890422). The following settings can be made with the DTM: ■ Measurement mode (RTD, TC, low volt- age, line compensation) ■ Measuring point (32 freely selectable char- acters) ■ Temperature (°C or °F) ■ RTD connection mode (2, 3 and 4-wire technology) ■ Cold-junction compensation (internla or via external RTD) NOTE: If the thermo- couple leads are led up to a temperature measurement amplifier, we recommend to use the cold junction compensation mod- ule IN IM 3-CJT from TURCK (ident-No.: 6900524). ■ Measuring range mapped on the power source ■ Output current (0/4…20 mA) ■ Fault current (0 resp. < 20 mA) The signals are transformed according to ITS 90/IEC 584 for thermocouples and according to IEC 751 for Pt100 RTDs and provided tem- perature linear at the current output. ■ Input for Pt100/ Ni100 resistors, thermo- couples and millivolt signals in 2, 3 or 4- wire technology ■ Suitable for fast temperature changes, starting with a thermal gradient of 200 µV/s ■ Parameterized using PACTware ■ Output: 0/4…20 mA ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ ATEX, IECEx, CFMUS, UL, TR CU, IN- METRO, CCOE ■ Installation in zone 2
