PROBLEM TO BE SOLVED: To easily perform wiring check between a remote terminal and a terminal stand, and to suppress the damage of a normal system circuit in the remote terminal. SOLUTION: FA equipment includes a circuit 16 for wiring check for receiving power supply from a power source for wiring check, and for outputting voltages for wiring check whose voltage values are different to a plurality of terminal parts 12 connecting an I/O cable; and a wiring check function malfunction preventing circuit 16 for, when at least either a system power source or an I/O power source which supplies power to the normal system circuit 11 is turned on, preventing the voltage for wiring check from being output from the circuit for wiring check to each terminal section.
