Vital Subsystem4.5. CRG (CODE RATE GENERATOR) BOARD 31166-261-XXThe Code Rate Generator Board is a Vital VPI II board that receives code ratecommands from the CPU II board. The received code rate commands are decoded andused to generate 8 coded outputs. The frequency and duty-cycle of the coded outputsare vitally verified by using an absence of current detector (AOCD). During the on andoff portions of an output’s coding cycle, data is circulated through the AOCD. Datareturned from the AOCD, coupled with other Numerically Integrated Safety AssuranceLogic (NISAL) processing verifications, are used to generate a message that the CRGboard sends to the CPU II board. The message received by the CPU II board from theCRG is used as part of the generation of the VRD checkword. All outputs are generatedusing a Double Break Output (DBO) DC-DC converter and, as such, are isolated fromeach other by >2000 Vrms and protected from undetected single fault failures.Figure 4-5.
