Function
The FRMU1000 is a speed-
monitor, a frequency-monitor
and a measuring-transducer in
one device.
2 limits with 1 relay each can be
programmed for under- or over-
speed, under- or overfrequency
or each monitoring of a range
(min/max).
The input for monitoring of speed
can evaluate signals from pro-
ximity-sensors 2- or 3-wire, npn-
or pnp. The display can be scaled.
Thus the real speed of a shaft can
be displayed, even though there
are several pulses per revolution,
e.g. from a cogwheel.
Application as Frequency-Relay:
Monitoring of frequencies in mains 16 2/3 to
400 Hz on maintaining a range (min/max).
Application as Speed-Relay:
Monitoring of overspeed or underspeed, each with
pre-alarm and alarm, monitoring of maintaining a ran-
ge (min/max) or monitoring of stop at machines and
equipment, e.g. at conveyors, escalators or lifts or for
monitoring of drive-belts.
Application as Measuring-Transducer:
In addition, the FRMU can be used as measuring-
transducer to convert the input-signal into a standard-
signal 0/4-20 mA or 0-10 V.
