Edition • 2023-07-21T16:28:44+02:00 Isolating transducer 1-channel IM43-14-CDRI The 1-channel IM43-14-CDRI isolating trans- ducer is designed to operate 2-wire transduc- ers (III) and to galvanically isolate and trans- mit the measured signals. Alternatively, ac- tive 2-wire transmitters (II) and passive 3-wire transmitters (I) can also be operated. The three limit values are set via teach but- tons at the front. The device is equipped with an analog output of 0/4…20 mA; In addition, three relay outputs for limit values are available. The unit of the measured value is freely selectable and indi- cated on a 2-line display. A green LED indi- cates operational readiness, 3 yellow LEDs indicate the switching status of the individual channels. At each of the three outputs a predefined set- point value can be monitored according to overshoot/undershoot. The switching hystere- sis is defined by programming the switch-on and switch-off point. Furthermore, a switch-off delay can be set individually for each output. 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 "excess of limit value". After that, the stored signal sequence 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 ■ Input circuit: 0/4…20 mA; 0/2…10 V ■ Output circuit: 0/4…20 mA, 3 independent limit value relays ■ Universal operating voltage ■ Monitors over and underrange of analog values and window limits ■ Connection of passive 2-wire and active 3- wire transmitters ■ Parameterized via PC (FDT / DTM), front- panel switch and HART® ■ Many diagnostic functions ■ Ring buffer for up to 8000 measured val- ues ■ Display ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ TR CU
