This unit is used to evaluate the signal of a wheel sensor. It translates the signals from the connected wheel sensor into an electric signal for a downstream system. Depending on its variant the isolating amplifier can be used to evaluate one double wheel sensor or two single wheel sensors. When it is configured for on double wheel sensor, the error outputs are connected to a signal and error if one occurs in one or both of the two connected system. When configured for a single wheel sensor, only the assigned error output of the system signals the error. Other variants differ in the type of sensor that can be used or in the minimum output pulse duration or in the pulse suppression of interfering signals:
