Ramped Valve Driver

GENERAL DESCRIPTION

This device is a ramped valve driver which accepts a setpoint potentiometer input from a control handle and drives a single

coil valve. It is pulse-width modulated and has adjustable acceleration/deceleration ramping. The PWM frequency is selected

by a jumper on the terminal strip. The threshold and full stroke forward outputs are adjustable. It does not have a reverse output.
