"Gurley Models HR2B and HR2CHigh Resolution Interpolators nn

The HR2B and HR2C interpolators increase the final resolution of your HR2C generates quadrature square waves up to 25 times the line count, and the HR2B provides 20X square waves. Both models include a quarter-cycle gated index and a "watchdog" circuit to monitor the analog waveforms from the encoder. 9710 modular rotary encoder or 9717 modular linear encoder by up to 80 times the line count on the disc or scale.
