ECDR-0203A Controller


Internal diagnostics make it possible to detect overvoltage and undervoltage conditions and coil failure conditions.

Outputs have short-circuit protection.

Supply voltage below 9 Vdc or above 32 Vdc will cause the controller to go to the safe mode of valve OFF and automatically resets.

The bi-color red/green LED provides quick status check.

The ECDR-0203A controller can be used in a wide range of applications, including transmission controls, vehicle traction controls, joystick controls, and harvesting function controls.

It can be specified for applications previously using the HydraForce EVDR7.
The ECDR-0203A is a robust electronic driver for solenoid-operated proportional valves. Its 32-bit processor provides high calculating power. It has three inputs that are configurable to multiple settings ranging from digital to analog. Two PWM outputs with configurable frequency. A single CAN bus allows CANopen and SAE J1939 communication protocols. The red/green LED signal provides quick status check. The molded enclosure has a scratch-resistant finish.

ECDR-0203A is configured with HF-Impulse software: an easy to use, web-accessible configuration tool available as a free download at www.hydraforce.com/electronics.

The controller accepts input from commonly available analog or SAE J1939 CAN/CANopen operator interface devices (joystick, potentiometer, sensors, etc.) The input signal drives the output current.
