System ASIC-based Replacement Modules Products and Services . Nuclear Automation . System ASIC-based Replacement Modules Background A number of Westinghouse plants have 7300 process protection and control systems.
Individual modules perform multiple functions.
Currently, there are 14 different 7300 card styles which replace more than 50 analog card types. Benefits The ASIC-based replacement cards have benefits over the current analog 7300 cards and, in limited cases, benefits over a full digital system replacement. Improved reliability over the current analog cards Reduced plant inventory of spare plants Combining multiple process functions on a single card reduces the number of cards in a channel Replacement does not impact plant field devices and cabinet wiring Reduced power consumption, lower cabinet operating temperature Description The ASIC-based replacement module preserves the current architecture of the 7300 system. Functions of the main board include power supply and distribution, input signal conditioning, analog outputs, and digital actuation outputs. There is a PM that corresponds to each 7300 series card.
