Edition • 2023-07-21T16:27:56+02:00 Temperature measuring amplifier 1-channel IM34-14EX-CDRI The 1-channel Ex-area temperature measur- ing 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, poten- tiometers or low voltages can be mapped lin- early 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 prede- fined trigger event, like for example "limit val- ue exceeded". After that, the stored signal se- quence can be read out. The device can be parametrized and config- ured 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 pa- rameters 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 tem- perature linear at the current output. Cold junction compensation of thermocouples is either realized via an externally connected Pt100/Ni100 resistor, via temperature mea- sured inside the amplifier or via an individually adjustable constant temperature value. ■ Parameterized via PC (FDT/DTM), front- panel switch or HART ■ Ring buffer for up to 8000 measured val- ues ■ Display ■ Input for Pt100/ Ni100 resistors, variable resistors, thermocouples and millivolt sig- nals ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ ATEX, IECEx, CFMUS, TR CU, KOSHA ■ Installation in zone 2
