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
+/- 5 Volts
+/- 4 Volts
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.
