EDAC2 ENCODER DIGITAL TO ANALOG CONVERTER

EDAC2 Product Description

The EDAC2 converts the A and B quadrature output of an incremental encoder into a proportional voltage 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 12-bit DAC that converts the 12-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 index, reverse rotation, midrange reset, and range limit counting. Full-scale output in 10V mode is actually 9.962V.

The EDAC2 has an internal counter that you may reset in three ways: by pressing the reset button, power cycling the unit, or enabling the reset on the encoder index. The reset may be configured to either mid-range or zero volts.

The EDAC2 also provides a TTL logic level output bit, which changes the state to indicate the analog voltage output's polarity.

Power is provided by an external power supply that provides +5VDC to an external encoder through the encoder input connector. A three-position screw terminal block provides the analog output connections and logic level direction bit output.
