An input-output device includes an input circuit unit including an input-signal-setting storing unit that stores a plurality of ON conditions of the input signal and an input circuit that determines whether any one of the ON conditions of the stored input signal holds, a computing unit including an output-signal-setting storing unit that stores information in which the ON conditions of the input signal, output ports for outputting an output signal, and specifications of the output signal are associated and an output-signal selecting unit that generates, on the basis of a determination result of the input circuit and the stored information, an output command indicating the output ports and the specifications of the output signal, and an output circuit unit including an output circuit that outputs, to the output ports indicated by the output command, the output signal according to the specifications indicated by the output command.

Control device having at least one electrical switching device, configured to provide electrical power to an associated load and arranged between a supply connection and a load connection and having at least one processing device, electrically connected with an input interface, with the at least one electrical switching device and with the load connection wherein it is provided that between the supply connection and the load connection parallel to the switching device an electrical resistor means is arranged, in order that when the switching device is open it forms a voltage divider with the load and allows a monitoring of the load connection independently of the switching state of the switching device.
