The EEA-PAM-5**-A-32 series made by Eaton Vickers composes a variety of proportional control valve units which are capable of regulating and measuring aspects of hydraulic systems. These units have a total of 5 voltage inputs, one of which is an inverter, and a current input range which goes from 0 to 20 milli amps. Every monitor point on the front of A-32 control cards is attached to a brightly colored LED indicator. The LVDT spoon position signal or the current of the solenoid can be read through the front of the panel at the monitor points. These amplifier cards are very user friendly and safe. All units are equipped with overload protection for power surges.
