About the 531X116SHAAAG1
The GE 531X116SHAAAG1 shield card manufactured by the GE Drives Department out of Erie, PA, is a very basic component card that is not a PCB. The shield card serves to protect the board which it is placed up against and creates a barrier necessary for functionality in certain environments. Unlike most PCBs the 531X116SHAAAG1 does not actually have traces or components printed onto it and instead it is a specially designed quasi translucent material.
Also printed on the 531X116SHAAG1 board itself is another part number F31116SHAAAG1. The card features two small holes on one end which can be used to attach the card to whichever board it is installed to protect.
