The rotation speed monitor IM21-14EXCDTRI monitors frequencies, rotation speeds

and pulse trains of rotating motor, gear or turbine parts according to over or undershoot of

adjusted limit values. The current value is indicated on a display on the front of the device.

Intrinsically safe sensors acc. to EN

60947-5-6 (NAMUR) can be connected. Depending 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 configured 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 parameters 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 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.

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.
