VS111-800-20

The electronic plug amplifier VS 111 provides control for proportional pressure, directional, and throttle valves. The plug amplifier may be mounted directly on the proportional solenoids and secured with a screw. The output of the amplifier supplies DC current for con- trolling one proportional solenoid. This current is proportional to the command signal at the input of the amplifier. Through this, together with a pro- proportional valve, an infinitely variable adjustment can be made to the pressure or flow.
