IO423: Synchro and Resolver I/O Module

A Synchro and Resolver I/O Module.

The IO423 is a 1- to 4-channel 16-bit Synchro/Resolver-To-Digital Converter offering a conversion accuracy of 2 arcmin + 1LSB.  
This I/O module supports Synchro and Resolver measurements in Simulink® with programmable resolutions of 10, 12, 14 or 16 bits. Signal conditioning adapters installed on the IO423 can adapt the Synchro/Resolver signal levels and configure the optional reference oscillator input/output. In addition, the module provides a 4 V velocity output to replace a tachometer. 
This I/O module is ideal for closed-loop controls and hardware-in-the-loop simulations using MATLAB® and Simulink®

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.
