Edition • 2023-07-21T16:26:47+02:00 Rotation speed monitor 1-channel IM21-14EX-CDTRI The rotation speed monitor IM21-14EX- CDTRI monitors frequencies, rotation speeds and pulse trains of rotating motor, gear or tur- bine parts according to over or undershoot of adjusted limit values. The current value is indi- cated on a display on the front of the device. Intrinsically safe sensors acc. to EN 60947-5-6 (NAMUR) can be connected. De- pending on the settings, the line is monitored for wire-break and/or short-circuit. In the event of an input circuit error the relays drop out, the transistor is blocked and the Pwr LED changes to red. 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 At each of the two relay outputs a predefined limit value can be monitored. The two relays also monitor overshoot/undershoot of window limits. The transistor output can also be used as a pulse divider. The measured value is per- manently written to a ring buffer with space for 8000 values. The writing process is stopped with a predefined trigger event, like for ex- ample "excess of limit value". After that, the stored signal sequence can be read out. A switching hysteresis is defined by setting a switch-on and off point. A switch-off delay can also be set to avoid shut down due to sudden frequency hops. ■ Monitoring of limit values and ranges ac- cording to over and underrange ■ Operating range 0.06…600,000 min ■ Pulse output Ex [ic Gc] II C/II B ■ Parameterized via PC (FDT/DTM), front- panel switch or HART ■ Ring buffer for up to 8000 measured val- ues ■ Display ■ Complete galvanic isolation ■ Input reverse-polarity protected ■ ATEX, IECEx, CFMUS, TR CU, NEPSI, TIIS, Kosha ■ Installation in zone 2
