Description
Turck 1-channel Rotational Speed Monitor IM21-14-CDTRI Drehzahlwachter 7505650 20-250V New
Overview
The rotation speed monitor IM21-14-CDTRI analyses frequencies, rotation speeds and pulse trains of rotating motor, gear or turbine parts according to over or undershoot of adjusted limit values. A display at the front indicates the current value.
If NAMUR sensors are connected, the line is monitored according to wire-break and/or short-circuit. In case of input circuit error the relays drop out, the transistor is inhibited and the power LED (Pwr) changes to red.
The device can be parametrized and configured via PC (FDT/DTM). For this, connect the device to the PC via the 3.5 mm jack plug at the front (the matching transmission cable IM-PROG III can be ordered separately from TURCK). A basic scope of parameters can be set via buttons and display at the front or remotely via the current interface and HART.
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 permanently written to a ring memory 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.
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.
