Selco E7800.0710 Motorized Potentiometer
The E7800 Motorised 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.
The potentiometer can easily be replaced when installed. There are access from the back of the device, when the four corner screws are removed. With an alan key the coupling can be taken of the potentiometer shaft, and a new potentiometer can be installed in the reverse order.
The supply to the unit is so it only has active power when movement is needed. The neutral or minus is connected at all times, but only when movement is needed is the line or positive connected to either a terminal for increase or for decrease.
