PROam21
The PROam21 valve amplifier has been specially developed to work well with AMCA’s proportional hydraulic control valves, and can be used as an amplifier for both the M and the APV series.
There are several input signals that the PROam21 can work with:
- +/- 10 Volts
- +/- 8 Volts
- 0…5…10 Volts
- 0…4…8 Volts
- +/- 5 Volts
- +/- 4 Volts
- 4…12…20 mAmp
- 4…20 mAmp
Manual (analogue) adjustment is possible on-site with a screwdriver – a function highly appreciated by mechanics. The amplifier has an adjustable ‘Ramp-up, Ramp-down’ which is useful when commissioning. The IP class of the PROam21 is IP20.
