Abstract
A device for diagnosing signal status includes a transformer, a signal generating unit, a device-to-be-driven, a current measuring unit, and an intermediate tap. The transformer includes a primary coil and a secondary coil. The signal generating unit is arranged for generating an alternating voltage and is connected to the primary coil. The device-to-be-driven is arranged for performing measurement, drive, or control and is connected to the secondary coil. The current measuring unit is arranged for measuring change in the current of the primary coil caused by electric power consumed for an action of the device-to-be-driven. In at least one embodiment, diagnosis of signal status in the measurement, drive, or control by the device-to-be-driven is performed based on the measurement result of said change in current. The intermediate tap is provided to the primary coil and configured to be connected to the current measuring means.
