The present disclosure relates to a sensor system having a shared communication interface that transmits sensor signals having independent channel protection data from a plurality of sensors. In some embodiments, the sensor signal has a plurality of sensors that independently generate sensor signals corresponding to a sensed quantity. A plurality of channel protection elements respectively receive one of the sensor signals and to introduce channel protection data into the received sensor signal to generate a channel protected sensor (CPS) signal. A shared communication interface receives CPS signals from one or more of the channel protection elements and to selectively provide the CPS signals onto a transmission line according to one or more communication protocols. By introducing channel protection data to the sensor signals upstream of the shared communication interface, a same communication interface can be used to transmit channel protected sensor signals from a plurality of independent sensors.
