- Motrona SI251 Sine/Cosine Interpolator for Sine/Cosine Encoders
Product Description
SI251 Sine/Cosine Interpolator for encoders & similar measuring systems convert output signals into incremental quadrature output signals either single ended HTL or differential TTL/RS422. The adjustable multiplier (1:5 to 1:50) and the programmable divider (1:1 to 1:128) determine the interpolation rate. For the 18-30Vdc power supply use the GDA18-24A 24Vdc/750mA.
