Electro-Craft Antique Servo question

Hi everybody,

Can someone tell me the distinction between an Electrocraft H-4050-P-H00AA servo, and an Electrocraft S-4050-P-H00AA servo? I've got data on the H series, but cannot find anything at all on the S series. Hoping they are electrically the same.

Thanks,

TM

Allen Bradley owns the Electrocraft brand. They got it when they acquired Reliance. Try getting in touch with someone who has been involved with AB or Reliance motion control options since the mid to late 1980s.
