A multifunctional signal isolation converter (10) is arranged in a safe area (20), and is applied to an electronic apparatus (40) arranged in a dangerous area (30). The multifunctional signal isolation converter (10) includes a microprocessor (108) and a power supply unit (116). The microprocessor (108) determines whether internal functions of the multifunctional signal isolation converter (10) are normal or not to obtain a first judgment value. The electronic apparatus (40) sends an input signal (42) to the microprocessor (108). The microprocessor (108) determines whether functions of the electronic apparatus (40) are normal or not to obtain a second judgment value according to the input signal (42). The microprocessor (108) controls whether the power supply unit (116) supplies a driving power (122) to the electronic apparatus (40) or not according to the first judgment value and the second judgment value.
