Edition • 2023-07-21T16:27:59+02:00 Temperature Measuring Amplifier 1-channel IM34-11EX-CI/K51 The 1-channel Ex-area temperature measur- ing amplifier IM34-11EX-CI/K51 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 ex- ternal cold junction compensation for the ther- mocouple or as independent measuring input. With the software tool Device Type Manager (DTM), the device can be configured and pa- rameterised via PC. For this, connect the de- vice 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 technol- ogy) ■ Measuring range, start ■ Measuring range, end ■ 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 compen- sation ■ 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 tem- perature linear at the current output. ■ Input for Pt100/ Ni100 resistors, thermo- couples and millivolt signals in 2, 3 or 4- wire technology ■ Parametrized via PC using PACTware ■ Output: 0/4…20 mA ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ ATEX, IECEx, CFMUS, UL, TR CU, IN- METRO ■ Installation in zone 2
