ABT Replacement Board
The ABT board connects to the generator shaft encoder and converts its electronic signals to fiber optics. Due to the extensive failures of the main connector on these boards, and its associated single-sided printed circuit board connection pads, a new board was developed by ReNu Controls. This board is pin-for-pin compatible with a more modern interface connector, and several important improvements including:
• A double sided circuit board providing better levels of shielding and mechanical integrity.
• A lower profile terminal block to lower the leverage and forces applied to the connectors solder joints when compared to the original.
• Improved transient protection for the critical generator shaft encoder.
• Reduced fiber optic transmitter LED current to help provide for longer life.
