Abstract: An input/output module is configured to achieve at least one of a function of acquiring a measurement signal from a measurement target and a function of outputting data. The input/output module includes a casing, a rotational connector disposed on the casing, the rotational connector including an arc-shaped notch, the rotational connector being configured to interlock with a connection mechanism of a base to serve as a rotation point so that the input/output module is rotatable to get connected to the base and a latch-shaped fixer configured to fit into a groove formed in at least one of an upper inner surface and a lower inner surface when the input/output module is pushed into a slot having the upper inner surface and the lower inner surface to get connected.

Abstract: An input/output module is commonly usable to a recorder and a data logger. The input/output module includes an input/output unit and a power unit. The input/output unit is configured to achieve at least one of a function of acquiring a measurement signal from a measurement target and a function of outputting data. The power unit is configured to supply an operation voltage to the input/output unit The power unit includes an insulated power device. The power unit is configured to use a voltage, which has been converted by the insulated power device from a power supply voltage, as an operation voltage when the input/output module is connected with a base of the data logger and the power unit receives a power voltage supply via the base. The power unit is configured to use a power supply voltage as the operation voltage, when the input/output module is connected with the recorder and the power unit receives the power voltage supply from the recorder.
