The Hydraforce 4210080 (4210080) is a highly versatile and compact plugin-style valve driver, specifically engineered for hydraulic proportional valve applications. This microprocessor-based device can be configured to drive either one or two coils, accepting inputs via SAE J CAN or an independent signal. The EVDRA model of the controller is adept at proportionally controlling one or two coils according to a user-defined metering profile, which can be set to provide either a straight-line or multi-sloped output. Configurations and adjustments are made simple with the use of HFImpulse software, a user-friendly, web-accessible tool provided by Hydraforce for free download. This software enhances the flexibility of the EVDRA by allowing precise customization of its operational parameters. The controller itself features two output LEDs on its front panel for easy monitoring of its status. In terms of operation, the EVDRA accepts input from commonly used analog or J CAN operator interface devices such as joysticks, potentiometers, and sensors. It dynamically adjusts the output current based on these inputs at a user-defined ramp rate, ensuring accurate and proportional metering of the hydraulic valve. As input changes occur, the output adapts accordingly to follow the predefined metering profile, enabling optimal system response. The unit is also equipped with robust built-in diagnostics that detect and respond to fault conditions such as supply voltage drops below . Vdc or any short/open circuit issues. These safety features ensure that in any fault condition, outputs are automatically deactivated to prevent system damage. Moreover, multiple configurations or "personalities" are available for this controller model to cater to specific application needs—ranging from general-purpose use (EVDRA) to specialized functions like fan control (EDFRA) and configurable options (ECDRA). Each configuration is designed to optimize performance in targeted applications.
