Electronic configurable valve driver



The ECDR-0506A is a robust electronic driver for solenoid-operated proportional valves. Its 32-bit processor provides high calculating power. It has six inputs that are configurable to multiple settings ranging from digital to analog. Five outputs, including four PWM closed loop outputs and one PWM open loop output, have configurable frequency. A single CAN bus allows CANopen and SAE J1939 communication protocols. The red/green LED signal provides quick status check. The molded enclosure has a scratch-resistant finish.

The ECDR-0506A controller can be used in a wide range of applications, including transmission controls, vehicle traction controls, joystick controls, and harvesting function controls. It can be specified for applications previously using the HydraForce EVDR4, EVDR5, or EVDR7.

ECDR-0506A is configured with HF-Impulse software: an easy to use, web-accessible configuration tool available as a free download atwww.hydraforce.com/electronics.


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

Diagnostic Features

  • Internal diagnostics make it possible to detect over/under voltage conditions and coil failure.
  • Outputs have short-circuit protection.
  • Supply voltage below 9 Vdc or above 32 Vdc will cause the controller to go to the safe mode of valve OFF and automatically reset.
  • The red/green bi-color LED provides quick status check.
