Frequency- and Speed Relay FRMU1000 / FR1000
Frequency- and Speed Relay
with integrated Measuring Transducer
Part number
Product description
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 overspeed, under- or overfrequency or each monitoring of a range (min/max).
The input for monitoring of speed can evaluate signals from proximity-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 range (min/max) or monitoring of stop at machines and equipment, e.g. at conveyors, escalators or lifts or for monitoring of drive-belts.
Applications as Measuring Transducer (FRMU only)
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.
