HydraForce has released two economical and efficient proportional valve drivers—the ExDR-0101A, a single output proportional driver with serial communications for configuration, and the ExDR-0201A, a dual output driver with SAE J1939 CAN communications.

  • Work as economical stand-alone units or in distributed CAN systems
  • Single or dual output control
  • Reliable operation outdoors; can tolerate extreme temperature, vibration and moisture 
  • Accept a variety of inputs and CAN messages to control a proportional valve to a user-defined metering profile
  • Feature compact on-valve mounting with integrated Deutsch DT-Series connectors for an IP rating of 69K
  • CE qualified
  • Built-in diagnostics detect fault conditions in the input or output signals and automatically deactivate the output until the condition is corrected
  • LED indicator(s) communicate output state or error conditions
  • Configurable through HF-Impulse, a free, easy-to-use software tool available for download at www.hydraforce.com/electronics which sets all parameters for operation and can also flash the driver with firmware updates
  • Multiple personalities are available for each driver. General purpose drivers EVDR-0101A and EVDR-0201A drive one or two coil outputs with a user-defined metering profile featuring up to three breakpoints, and independent input/output ramps. The 0201A version can operate as a slave, responding to CAN messages.
  • Time-based proportional drivers ETDR-0101A and ETDR-0201A use a digital input to trigger the ramping sequence
  • Proportional reversing fan control EFDR-0201A modulates fan speed based on input from a temperature sensor, or CAN messages from the engine control module. The second output controls a reversing function to periodically clean debris from the vehicle's radiator.
