RDK 9316 – Resolver Demodulator

RDK 9316 is a compact, reliable and highly versatile Resolver-to-digital conversion module.

All commonly used Resolvers can be easily connected to the RDK 9316 without any additional signal adaption. The module has a built-in excitation oscillator inclusive power stage which can drive most Resolvers directly without the necessity of an external power booster. All module parameter are interactively adjustable via soft ware.

A sensor-detection functionality automatically adjusts the module to the specific sensor ratio. The RDK 9316 accepts a wide voltage supply range from 9 V to 36 V and provides galvanic isolation between the cRIO rack and the demodulator interface.

Typical Applications

  • Data logging of resolver
  • Engine control
  • Position control
