Littelfuse E7800.0700 - Motorized Potentiometer 24V DC, 10k. The E7800 Motorized Potentiometer is typically used as an interface between increase/decrease relay contacts (or push buttons) and a device requiring control by an external potentiometer (e.g. the speed trim of an electronic governor). All three wires of the potentiometer are directly accessible on external connection terminals, thus providing the best possible flexibility for almost any application. A special version of the E7800 with DC voltage output is also available. The DC output voltage follows the position of the potentiometer. The design of the E7800 ensures that the potentiometer will “remember” its position although supply is lost

Littelfuse M0500.0080 - Tacho Voltage Detector. 400V / 12-24 DC.. The M0500 is an accessory unit for the M2000 Engine Controller and the M2100 Emergency Controller. The speed output signal is typically used in conjunction with the M2000 or M2100. This signal is used by the M2000/M2100 to provide crank disconnect at 33percent of nominal speed and over speed alarm (and optional engine shutdown) at 115percent of nominal speed. The M0500 also includes an output which tells the M2100 Emergency Controller whether or not the generator output voltage is within the nominal range.
