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)

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

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
