EVDR-0201A

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

Overview

Description

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 input or an independent signal. TheEVDR-0201A proportionally controls one or two coils to a user-defined metering profile. The profile provides either a straight-line or multi-sloped output that you configure with HF-Impulse software: an easy to use, web-accessible configuration tool available as a free download at www.hydraforce.com/electronics. Two output LEDs are located on the front.

Operation

The controller accepts inputs from commonly available analog or J1939 CAN operator interface devices (joystick, potentiometer, sensors, etc.). The input signal drives the output current to the user-defined ramp rate, enabling accurate and proportional metering of the hydraulic valve. As the input changes, the output follows the defined metering profile, allowing optimum system response. You can configure the unit for direct valve operation. Built-in diagnostics detect fault conditions that automatically deactivate the outputs.

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
