Technical Questions & Answers

• How does the TMR voting system work?
• Two of three controllers must simultaneously vote to close relays, creating conduction paths through six form devices for trip activation.
• What speed sensing capability does the board provide?
• Nine passive pulse devices sense toothed wheels, measuring turbine speed across three separate X/Y/Z sections for redundancy.
• What voltage levels do the output contacts support?
• The board provides two contact sets operating at 24 VDC and 125 VDC levels for different trip system requirements.
• How does the relay short detection system work?
• Sensing circuits monitor voltage across relays when commanded open, detecting shorts and generating alarm signals to PPRO packs.
• What expansion capabilities does the board offer?
• Daughterboard connectors allow optional feature expansion, while jumper blocks enable speed input distribution flexibility.
