It provides interfaces for the PPRO I\/O pack, conditions speed input signals, and accepts generator and bus voltage signals through onboard potential transformers (PTs). Its DC-37 connector supports cable connection to a backup trip relay terminal board, while dedicated terminal assignments separate voltage inputs, speed inputs, and reserved control connections.\u003c\/p\u003e\n\u003ch3\u003eFunctional Overview\u003c\/h3\u003e\n\u003cp\u003eThe IS200SPROH1ACC supports signal acquisition for speed monitoring and generator-bus synchronization functions. Its onboard PTs provide isolated voltage signals for use by the associated control hardware. The board also provides a physical interface for exchanging signals with the Mark VIe backup trip relay terminal board.\u003c\/p\u003e\n\u003ch3\u003eSpeed Inputs and PPRO Interface\u003c\/h3\u003e\n\u003cp\u003eThe board connects to the PPRO I\/O pack, which processes speed-related input signals. Terminals 19-24 are assigned to speed inputs, while terminals 7-15 are routed to the JA1 PPRO connector for designated or reserved control functions. Terminals 5-6 and 16-18 have no board connection according to the supplied description.\u003c\/p\u003e\n\u003ch3\u003eGenerator and Bus Voltage Inputs\u003c\/h3\u003e\n\u003cp\u003eTwo single-phase potential transformers provide voltage sensing for the generator and bus. Each PT has a nominal secondary output of 115 V rms, with an input loading requirement below 3 VA. The specified synchronization voltage range is 75-130 V rms.\u003c\/p\u003e\n\u003cp\u003eEach PT input has a 1,500 V rms magnetic isolation barrier. The stated wiring capability is up to 1,000 ft using 18 AWG cable. These conditions should be checked against the system wiring design and applicable Mark VIe documentation before installation.\u003c\/p\u003e\n\u003ch3\u003eTerminal Mapping and Connectors\u003c\/h3\u003e\n\u003cp\u003eThe supplied terminal assignments identify the following connections:\u003c\/p\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eTerminal or Connector\u003c\/th\u003e\n\u003cth\u003eFunction\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminals 1-4\u003c\/td\u003e\n\u003ctd\u003ePotential transformer (PT) inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminals 5-6\u003c\/td\u003e\n\u003ctd\u003eNo board connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminals 7-15\u003c\/td\u003e\n\u003ctd\u003eReserved control connections routed to JA1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminals 16-18\u003c\/td\u003e\n\u003ctd\u003eNo board connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminals 19-24\u003c\/td\u003e\n\u003ctd\u003eSpeed inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJA1\u003c\/td\u003e\n\u003ctd\u003ePPRO I\/O pack connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eJA3\u003c\/td\u003e\n\u003ctd\u003eBackup trip terminal board cable connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC-37 connector\u003c\/td\u003e\n\u003ctd\u003eInterface for the backup trip relay terminal board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eVerify connector assignments against the installed board revision and its wiring documentation before connecting field wiring.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eIS200SPROH1ACC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric (GE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMark VIe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eBackup Protection Terminal Board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssociated I\/O Pack\u003c\/td\u003e\n\u003ctd\u003ePPRO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage Sensing\u003c\/td\u003e\n\u003ctd\u003eTwo single-phase potential transformers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePT Secondary Output\u003c\/td\u003e\n\u003ctd\u003e115 V rms nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePT Input Loading\u003c\/td\u003e\n\u003ctd\u003eLess than 3 VA per input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSynchronization Voltage Range\u003c\/td\u003e\n\u003ctd\u003e75-130 V rms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePT Magnetic Isolation\u003c\/td\u003e\n\u003ctd\u003e1,500 V rms barrier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Stated Cable Length\u003c\/td\u003e\n\u003ctd\u003e1,000 ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStated Cable Size\u003c\/td\u003e\n\u003ctd\u003e18 AWG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-30 to 65 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e15.9 cm high x 17.8 cm wide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturing Origin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnology\u003c\/td\u003e\n\u003ctd\u003eSurface-mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the function of the IS200SPROH1ACC?\u003c\/p\u003e\n\u003cp\u003eA: It provides termination and signal interfacing for the Mark VIe backup protection arrangement, including speed inputs, generator and bus voltage sensing, and the backup trip relay terminal board connection.\u003c\/p\u003e\n\u003cp\u003eQ: What voltage signals does the board support for synchronization?\u003c\/p\u003e\n\u003cp\u003eA: The supplied specifications identify two PT inputs with nominal 115 V rms secondary outputs and a synchronization voltage range of 75-130 V rms.
