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.
