Product description

  • Speed monitoring on rotating machine parts
  • Monitoring of cyclic movements
  • General monitoring of pulse sequences (transportation, conveyors, production systems),
  • Monitoring of pulse frequency (e.g. flow sensors, anemometers)

Technical specifications

Enclosure design: Switch cabinet
Width: 45 mm
Output contacts: 2 x 2 Wechsler
Measuring range max.: 120000 IPM
Type: MH 9055/5__

Advantages

  • Protection of persons, machines and products
  • Easy setting
  • Universal input, for configuration of different sensors
    (PNP, NPN, 2-wire, contact, voltage)
  • With fast reaction at low speed

Features

  • According to IEC/EN 60 255-1
  • Monitoring of 2 frequency levels (e.g. underspeed / standstill and overspeed)
  • Separate relay outputs for under- and overfrequency (1 or 2 c/o contacts each)
  • As alternative window operating mode (monitoring of a speed range)
  • Response value for over- and underspeed / frequency separately
    adjustable in 10 ranges 1 ... 120.000 IPM or 0,15 ... 20.000 Hz
  • Most fast reaction time also at low speed by time period measurement of the input frequency
  • As option with input for NAMUR-sensors with sensor and
    wire protection against interruption and short circuit
  • Programmable via termminals:
    - Start up time delay 0 ... 50 s or controllable
    - Alarm delay time of 0 or 0.5 s
    - With manual reset or auto reset
  • LED-indication for auxiliary voltage, measuring input and output relay;
    additional LED for indication of wire- / sensor failure at NAMUR-input
  • Auxiliary voltages AC 230 V and DC 24 V in one unit
  • MH 9055 with wide input range for auxiliary voltage
    AC/DC 24 ... 60 V or AC/DC 110 ... 230 V (only 2 x 1 C/O)
  • As option with analogue output, proportionally to speed
  • 2 possible contacts
    MK 9055N/5_ _ 2 x 1 changeover contacs
    MH 9055/5_ _: 2 x 2 hangeover contacs or wide range aux. voltage
  • 2 possible compact designs
    MK 9055N/5_ _: Width 22,5 mm
    MH 9055/5_ _: Width 45 mm
