Kollmorgen PRD-B040EAlZ-6 Resolver-to-Digital Converter
Product Category: Feedback Interface — Resolver-to-EnDat/BiSS Converter
Product Introduction:
The PRD-B040EAlZ-6 is a high-precision resolver-to-digital converter module from Kollmorgen. It converts analog resolver signals into digital EnDat 2.2 or BiSS-C output, enabling legacy resolver-based motors to interface with modern Kollmorgen servo drives that require digital feedback.
