What is the purpose of each of the 'signal conditioners' (6000F085 / AH170 / F125) shown in the illustration? EL-0094 A. Convert the varying signal from its particular sensor and deliver a corresponding signal of 0 - 10 volts to the 'setpoint module'. B. Drive the Data and Alarm Loggers directly for a continuous record of sensor operating conditions during the time the engine(s) may be on-line. C. Supply two or three different D.C. voltages to their respective motors which in turn rotates to indicate relative input conditions. D. Receives constantly updated information from the 'setpoint module' in order to keep the pressure or temperature at its sensor at set limits.
