Abstract
An electro-pneumatic device includes a sensor portion and a valve portion. The sensor portion, which includes a sensor, receives and transmits electronic control signals of a plurality of frequencies. The sensor portion is powered by a first of the frequencies of the received control signals. The valve portion electrically communicates with the sensor. The valve portion includes a valve that is alternately set to an open state and a closed state based on a second of the plurality of frequencies of the received control signals. The sensor senses a delivery pressure of the valve and transmits electronic data signals representing the delivery pressure at a third of the plurality of frequencies.
