ECDR-0203A Controller

 

DIAGNOSTIC FEATURES:
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.


APPLICATION NOTES
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.
DESCRIPTION
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 outputs, including one PWM closed loop output and one PWM open loop output, have 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.

OPERATION
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.
