ESDR-0201A controller two output, one input, closed-loop PID control



the ESDR-0201A is a compact plug-in style, microprocessor based, closed-loop PID valve driver designed for use in hydraulic proportional valve applications. The controller receives a command via CAN bus and drives the two outputs through a pid loop receiving feedback signal from the 0-5 V input. a 5 Vdc reference output (250 mA) is provided for powering an external sensor. The ESDR-0201A is designed to work with hydraforce proportional valves with integrated LVDT position sensor, however it can function as a stand-alone PID control. PID tuning parameters are configurable using HF-Impulse software: an easy-to-use, web-accessible configuration tool available as a free download at www.hydraforce.com/electronics.

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.
  • When the fault is corrected, the controller returns to standard operation.
