EDIVIDE Encoder Resolution Divider

Overview

  • Divides resolution by any number between 1 and 4096
  • Produces 90 deg. quadrature with 50% duty cycle
  • Low cost solution for custom resolutions
  • Tracks encoder position in real-time from DC to 1 MHz
  • Positive finger-latching connectors
  • Optional DIN rail mount

The EDIVIDE divides the resolution of an optical incremental encoder by any integer number set by the DIP switch. The EDIVIDE draws its +5 V power from the encoder cable. It outputs quadrature codes with 50% symmetry and 90...

Product Description

The EDIVIDE divides the resolution of an optical incremental encoder by any integer number set by the DIP switch. The EDIVIDE draws its +5 V power from the encoder cable. It outputs quadrature codes with 50% symmetry and 90 deg. quadrature outputs. The index signal from the encoder is simply passed straight through from input to output with no change. It tracks bidirectional encoder inputs from DC to 1 MHz. DIN rail mounting is available.

Since incremental encoders are available with only limited resolution choices, the EDIVIDE greatly extends the possible choices. Set the DIP switch to the desired divisor in binary (i.e. to divide by 161, set the DIP switch to 128 + 32 + 1). It is best to cycle the power after any changes are made to the the DIP switch.
