- 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.
- Setting in Hz oder 1/min
- 5-digit display
- Analog output DC 0/4-20 mA or DC 0-10 V, free scaleable (with isolation to frequency-input U1/U2)
- 2 limits/ 2 relays
- programmable for each relay:
+ Monitoring of min, max or range
+ Hysteresis
+ Autoreset reclosing lock
+ Delay-time for switching an switching back down to 50 ms
+ Operating- or closed-current mode
- LEDs for state of relays and unit (Hz oder min-1)
- Storage of min- and max-values of the inputs
- Easy setting with 3 buttons
- Code lock against manipulatin of settings
- Universal power supply AC/DC 24-240 V
- Terminals pluggable
