    摘要： An electric device (6) capable of suppressing an influence of variation of a consumed current on a superimposed signal is provided. An electric device (6), which transmits a superimposed signal obtained by superimposing a data signal on the operation signal according to a state of an operating element to the outside, includes a current consuming part (620) configured to consume a current, and a current control part (623a) configured to control current consumption in a circuit including the current consuming part (620) such that current variation of the superimposed signal following variation of the consumed current in the current consuming part (620) is suppressed.

    摘要： A power supply circuit in a PLC is downsized. A power supply circuit (13) in a PLC includes a first node (31) that receives a DC voltage with a first level (V1), a second node (32) that outputs a voltage for driving a control unit (14), wiring (40) connecting the first and second nodes (31, 32), a first rectifier (37) on the wiring (40) having a forward direction from the first node (31) to the second node (32), a charger (34) for charging and discharging, a first converter (35) that converts a discharging voltage from the charger (34) into a DC voltage with a second level (V2) lower than the first level (V1) and outputs the voltage, and a second rectifier (36) connected between an output (46) of the first converter (35) and the second node (32) to have a forward direction from the first converter (35) to the second node (32).

    摘要： An electrical device configured to transmit or receive a signal related to an operation element and transmit a data signal using a small number of wirings is realized. An electrical device (6) includes a first terminal (11) and a second terminal (12) to which a pair of signal lines (21 and 22) is connected, an operation element (13) connected between the first terminal and the second terminal, and a transmission circuit (15) configured to operate using a voltage between the first terminal and the second terminal as a power source. The second terminal transmits an output signal according to a state of the operation element to the outside, and the transmission circuit superimposes a data signal on the output signal and transmits the data signal from the second terminal to the outside.
