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 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)
- As option with analogue output, proportionally to speed
- 2 possible contacts
