Abstract
A non-volatile 1-bit state storage including a first signal converter for converting a digital input signal into an analog intermediate signal and a second signal converter for converting the analog intermediate signal into a digital output signal. The first signal converter is provided with a non-volatile memory so that after an outage of a power supply voltage, the previously output analogue intermediate signal is restored. A bistable solid-state relay that assumes a bistable switching state by means of the non-volatile 1-bit state storage and restores this state after an outage of the power supply voltage.
Claims27
A non-volatile 1-bit state storage comprising:
- a signal converter configured to convert digital input signals into analog output signals comprising:
- an input configured to input the digital input signals;
- an output configured to output the analog output signals;
- and
- non-volatile memory for storing a current digital input signal of the digital input signals;
- and
- a bistable signal converter comprising an input in signal communication with the output of the signal converter;
- wherein after an interruption of a power supply voltage to the storage, the current digital input signal is again applied to the input of the signal converter.
