EC-34 Two Quadrature Encoder to Analog Converter - 1

• Converts any incremental encoder into an analog position sensor • 16 bits analog resolution • 0 to 4.095V or 0 to 10V unipolar output voltage • 4.095 or 10V bipolar output voltage operation • Reset can be configured to zero or mid-range • Simple DIP switch and defined programming Rack mounting are available The EC-34 converts the A and B quadrature output of an incremental encoder into a voltage that is proportional to the encoder position. The output from the encoder causes an internal 12-bit counter to count up or down. The output of the counter is fed into a 16-bit DAC that converts the 16-bit position count value to an analog voltage. Eight DIP switches are provided to select various options. The user can choose unipolar output mode with 0 to 4.095V or 0 to 10V output, bipolar output mode with ± 4.095V or ± 10V output, 1X or 4X counting, reset on index, reverse rotation, midrange reset and range limit counting. Full scale output in 10V mode is actually 9.962V. The EC-34 has an internal counter that may be reset in one of three ways: by pressing the reset button, power cycling the unit or enabling the reset on encoder index. The reset may be configured to either mid-range or zero volts. The EC-34 also provides with a TTL logic level output bit, which changes state to indicate direction of a rotary encoder shaft rotation or travel direction of linear encoder.
