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 terminals:
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 contacts
MH 9055/5_ _: 2 x 2 hangeover contacts or wide range aux. voltage
2 possible compact designs
MK 9055N/5_ _: Width 22,5 mm
MH 9055/5_ _: Width 45 mm
