Background

Westinghouse has developed new printed circuit cards for use in the solid state protection system (SSPS). The replacement printed circuit cards are the same in form, fit and function as the original cards, but also address obsolescence of the Motorola High Threshold Logic (MHTL) devices, which are designed to enhance reliability and include improvements for maintenance.

Description

  • Solves MHTL obsolescence issue
  • Is physically interchangeable with existing cards
  • Has enhanced reliability
    • Redundant drivers added to under-voltage driver card
    • Safeguard driver card output circuit improvements
  • Has improved maintainability
    • Additional test points
    • Status indications for all inputs and outputs added
    • Continuous self-testing
  • Meets or exceeds the electrical specifications of the existing cards

Qualification

The replacement printed circuit cards are qualified for use in accordance with the following:

Environmental – IEEE 323-1983

Seismic – IEEE 344-1987

Electromagnetic compatibility (EMC) and radio-frequency interference (RFI) – RegulatoryGuide 1.180, Revision 1
