PROam21 valve amplifier
PROam21
The PROam21 valve amplifier board has been specially developed to work well with AMCA’s proportional hydraulic control valves, and can be used as an amplifier board 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 Volt
+/- 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 fitters. The amplifier has an adjustable ‘Ramp-up, Ramp-down’ which is handy when commissioning. The IP class of the PROam21 is IP20.
