The Hydraforce 4204700 (4204700) is a state-of-the-art microprocessor-based valve driver, specifically engineered for hydraulic proportional valve applications. This compact plugin style device offers versatility and high performance, capable of driving either one or two coils. It utilizes either SAE J CAN input or an independent signal for operation, making it adaptable to various control systems. The EVDRA model allows for precise control over hydraulic valves by proportionally controlling the coils according to a user-defined metering profile. This profile can be configured to have either a straight-line or multi-sloped output using the HFImpulse software—a user-friendly, web-accessible tool provided by Hydraforce. The operational capabilities of the 4204700 include accepting inputs from commonly used analog or J CAN operator interface devices such as joysticks, potentiometers, and sensors. The input signals are then converted into output currents at the defined ramp rate which matches the user's specifications for accurate and proportional metering. Built-in diagnostics within the unit enhance reliability by detecting faults and automatically deactivating outputs if necessary, with built-in recovery upon fault correction. Moreover, this controller is designed with multiple configurations or 'personalities' to cater to specific needs across various applications. These configurations include General Purpose (EVDRA), Fan Control (EDFRA), and Configurable (ECDRA), each tailored to optimize performance in different operational contexts. Additionally, two output LEDs provide visual status indication directly on the front of the device, enhancing usability and monitoring in real-time application environments.
