The speed monitors MK 9055N/5_ _ und MH 9055/5_ _ monitors the rotational speed of motors. They recognise and monitor impulse signals of e. g. proximity sensors and protect machines and produced material or allows speed depending switching in production processes.

Features

According to IEC/EN 60255-1
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)
