It processes analog field signals used in gas turbine control, including thermocouple measurements, 4-20 mA inputs, LVDT signals, pulse rate inputs, and servo coil outputs. The module combines processor and application I\/O circuitry in a single assembly and supports simplex, dual, and TMR system configurations.\u003c\/p\u003e\n\u003ch3\u003eAnalog Signal Processing\u003c\/h3\u003e\n\u003cp\u003eThe PCAA assembly contains a processor board, two application-specific analog processing boards (BCAA and BCAB), and an integrated TCAS terminal board.
