Abstract: Embodiments of the present disclosure provide a protective circuit to be used in a digital output module, the digital output module comprises a first voltage source and at least an output terminal. The protective circuit comprises: a first sampling unit for sampling a first voltage relevant to the output current from the first voltage source, a first comparing unit for comparing the sampled first voltage with a first reference voltage, a control unit for generating a current regulating signal based on a result from the first comparing unit, and a current regulating unit for regulating the output current from the first voltage source based on the current regulating signal. This protective circuit provides overflowing and short circuit protection, and is cheap in cost.

Abstract: Embodiments of the present invention disclose a circuit structure and a method for reducing power consumption of a device including an active module and a passive module. The circuit structure comprises: an active module (22) comprising a main output voltage (221) for powering a load (26) via a first current control device (222) which is configured to control a current passing through the load (26), and an passive module (24) comprising a main output voltage (241) for when the active module (22) fails, powering the load (26) via a second current control device (242) which is configured to control a current passing through the load (26). The passive module (24) further comprises an auxiliary output voltage (243) for when the passive module (24) is in a backup state, powering the second current control device (242) so as to enable the second current control device (242) to be in a switching-on state. Further, the auxiliary output voltage (243) of the passive module (24) is configured to be smaller than the main output voltage (241) of the passive module (24).

Abstract: Disclosed are an apparatus and a method for transmitting an analog signal, and an analog signal multiplexer. The apparatus comprises a photocoupler to receive an input analog signal and transform the input analog signal into an output analog signal, which varies with the input analog signal in a manner of non-linearity. The apparatus further comprises a non-linearity correcting unit to receive the output analog signal and correct the non-linearity to output a corrected output analog signal. An analog signal may be transmitted with a photocoupler.
