About the IS200FOSBH1A
The IS200FOSBH1A is a Fiber-Optic Interface board. The board is used within the Innovation series drive as a distribution array board. The IS200FOSBH1A is designed to interface signals from the BICH and BPIH boards to bridge power devices. The IS200FOSBH1A takes gate driver status signals from the BICH/BPIH boards and multiplexes them on a per phase basis. Between these three boards (FOSB/BPIH/BICH) most signal processing, protective, gating, and feedback interface functions are provided for the DSPX Digital Signal Processor Control Board.
The IS200FOSBH1A is able to indicate bridge faults and can initiate soft-shutdown fault sequences when necessary. It has the ability to detect and signal missing or improperly connected cables. The IS200FOSBH1A receives input power from the GDPA High-frequency Power Supply board. The IS200FOSBH1A has a transformer and a 5V power supply. Tech support for the IS200FOSBH1A was provided by GE. Handling precautions as recommended by the manufacturer should be followed when replacing or removing the board. This IS200FOSBH1A device is not the originally-produced device of its specific Mark VI Series functionality; that would be considered the IS200FOSBH1 parent PCB not making use of this IS200FOSBH1A product's sole A-rated functional product revision. The IS200FOSBH1A is built with:
- 102 fiber-optic connectors
- each pair with a light emitting diode
- no fuses or any other kind of adjustable hardware
- two stab-on connectors
- two TP test points
- six board (plug) connectors
