Valve Drive Amplifier
GENERAL DESCRIPTION
The device is a free–standing amplifier mounted on 4 standoffs. Voltage from a sensor potentiometer, through the amplifier,
produces current to drive electrohydraulic actuators. Connections to the amplifier are via screw terminals with 3/16–inch
quick–connects. An external switch can change gain settings by shorting between two terminals.
