Description
Line Drivers are available for the HEDM-5500 series
encoders. The line driver oers enhanced performance
when the encoder is used in noisy environments, or when
it is required to drive long distances.
The HEDL-556x series utilizes an industry standard line
driver IC, AM26C31Q, which provides complementary
outputs for each encoder channel. Thus, the output of
the line driver encoder is A, A, B, B. Suggested line receiv-
ers are 26LS32 and 26LS33.
For additional information, please refer to:
HEDM-55xx/56xx datasheet.
