Description
A compact plug-in style, microprocessor based valve driver designed for use in hydraulic proportional valve applications. Configurable to drive a single coil using an independent signal. The ECDR-0101A proportionally controls one coil to a user-defined metering profile. >It is configured with HF-Impulse: an easy-to-use, web-accessible configuration tool available as a free download atwww.hydraforce.com/electronics.An LED output indicator is located on the front.
Operation
The controller accepts input from commonly available analog operator interface devices (joystick, potentiometer, sensors, etc.) The input signal drives the output current.
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.
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.
EVDR-0101A - General Purpose.
ETDR-0101A - Transmission Apps.
EGDR-0101A - Generator Control.
