Electronic Vehicle Controls - Valve Drivers - Configurable


Plug-in style, dual output valve driver, general purpose



A 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 or CAN Open input or an independent signal. The ECDR-0201A proportionally controls one or two coils to a user-defined metering profile. It is configured with HF-Impulse software; an easy-to-use, web-accessible configuration tool available as a free download at www.hydraforce.com/electronics.


The controller accepts input from commonly available analog or SAE J1939 CAN/CAN Open operator interface devices (joystick, potentiometer, sensors, etc.) The input signal drives the output current.

Diagnostic Features

  • Any supply voltage below 8.5 Vdc causes the controller to default to the valve-off mode.
  • The driver output drops and holds at the inactive stand-by condition.
  • Any short or open circuit condition is automatically detected as an error.
  • When the fault is corrected, the controller returns to standard operation.

Multiple Personalities

The EVDR controller is available in multiple configurations (personalities) to suit the needs of specialized applications. Choose the one that best fits your needs.

EVDR-0201A - General Purpose.

EDFR-0201A - Fan Control.

ECDR-0201A - Configurable.
