A CE-qualified, compact plug-in style, microprocessor based, valve driver designed for use in hydraulic proportional valve applications. Configurable to drive either one or two coils using SAE J1939 CAN input or an independent voltage, current, or resistance signal. The EVDR-0201 is designed to proportionally control one or two coils to a user-defined metering profile. The profile can provide either a straight-line or dual sloped output which is user configurable. An easy to use, web-accessible configuration tool is available as a free download at www.hydraforce.com/electronics
The controller will accept inputs from commonly available analog or J1939 CAN
operator interface devices (joystick, potentiometer, sensors, master controller, etc.).
The input signal drives the output current to the user defined ramp rate, enabling
accurate and proportional metering control of the hydraulic valve. As the input
changes, the output follows the defined metering profile allowing optimum system
response. The unit can be configured for direct valve operation. Built-in diagnostics
detect short to ground, over current or over voltage conditions which automatically
deactivates the outputs.
