するモジユール保護装置。 In an arithmetic processing device in which a modular circuit board having a plurality of connection terminals arranged in a row is replaceably mounted using a terminal connector provided in a module circuit board mounting part, a pair of protective terminals are provided in the module circuit board mounting part. A connecting tool is provided at the connecting terminal forming end of the modular circuit board, and the connection with the protective terminal connecting tool is realized after the connection between the connecting terminal and the terminal connecting tool is realized, and the connecting terminal is provided. and a pair of protective terminals that can be disconnected from the protective terminal connector before the terminal connectors can be disconnected from each other, and further connect the protective terminal connector to the protective terminal. A detection current power supply unit that passes a detection current between the protective terminal connector and the protective terminal, and an ON/OFF state of the detection current that is realized by a change in the connection state between the protective terminal connector and the protective terminal.
a detection unit that detects the FF and generates a detection signal;
A module protection device comprising: an operating current supply command unit that senses the detection signal and instructs the supply of an operating current that flows between the terminal connector and the connection terminal.
