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 dual coil
proportional valve. It is pulse-width modulated and has adjustable acceleration/deceleration ramping. The threshold, full
stroke forward and full stroke reverse outputs are adjustable.
It has a 12" pigtail with a 4-pin sealed Packard shroud connector for the power and output connections and a 12" pigtail with
3-pin (female) sealed Packard tower connector for the setpoint potentiometer connections. A bag assembly with mounting
hardware is shipped with the device. For mating connectors order bag assemblies K03384, 4-pin (female) tower connector
and K08630, 3-pin shroud connector.
