IO423: Synchro and Resolver I/O module

A Synchro/Resolver to digital converter with up to 4 channels for Simulink Real-Time

The IO423 is a 1- to 4-channel 16-bit Synchro/Resolver-to-digital converter I/O module offering a conversion accuracy of 2 arcmin + 1LSB. This I/O module for Synchro and Resolver measurements in Simulink supports programmable resolutions of 10, 12, 14 or 16 bits. Signal conditioning adapters installed on the IO423 are required to adapt the Synchro/Resolver signal levels and to configure the optional reference oscillator input/output. In addition, the module provides a 4V velocity output to replace a tachometer.

 Signal conditioning adapter:

  • Input ranges: signal conditioning adapters individually built to customer specification
  • Reference oscillator option available
  • High precision option available

MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2; Environment: GB 20°C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
