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.

Input/output module

A panel instrument to be mounted in a panel board, including: a main body having an outside dimension applicable to a first and a second panel instrument size standards; a display provided on one end of the main body and having an area that occupies a part of a front face of the panel board and is applicable to the first panel instrument size standard; a front panel mounted on a front face of the display; and a rear panel for holding the display with the front panel, wherein the rear panel has: first mounting holes that are provided on one diagonal line of the rear panel and correspond to a mounting hole standard applicable to the second panel instrument size standard; and second mounting holes that are provided on the other diagonal line and correspond to a mounting hole standard applicable to a third panel instrument size standard.

Panel instrument

A panel instrument apparatus of reduced size, comprising a printed circuit board on which light emitting elements and switches are mounted, and a panel cover to the rear of which the front face of the printed circuit board is attached. The panel cover comprises reflecting holes arranged in positions corresponding to the light emitting elements on the printed circuit board to guide light from the light emitting elements to the surface of the panel cover; and furthermore comprises resilient links and coupled thereto keys which are located in positions corresponding to the switches on the printed circuit board.
