FUNCTIONALLY EQUIVALENT PCBs

The present running 3-phase Electrical Locomotives using the design of MICAS S2 class of Electronic PCB’s are of late 1980’s vintage. Many components have already been declared obsolete by the OEM’s years ago. Due to this, the genuisness of many parts which are currently being purchased is not very certain. The failures are likely to increase in future and maintenance could be a serious problem.
To overcome such difficulties we have undertaken re-design of MICAS S2 electronic PCB’s retaining the same functionality and straight-away interchangeable. In this connection we have already developed 10 types of PCB’s namely: 1. UF B701 A01 Bus Coupler Board 2. UF B660 A01 Bus Coupler Board 3. AR B705 B01 Signal Routing Board 4. UA B630 A91 Signal Conditioning Board 5. UA B630 A93 Signal Conditioning Board 6. UA B630 A36 Signal Conditioning Board 7. AF B635 B08 Fibre Optic Interface Board 8. UR B512 D15 Digital I/O Board 9. KU B921 A01 Power Supply Board 10. UA B514 B33 Analog I/O Board
