Abstract

PURPOSE:To unify the analog output signal taken out from a reception module to a fixed output form by fixing the upper limit value and the lower limit value of an analog input signal to a certain upper limit frequency and a certain lower limit frequency to convert the analog input signal to a frequency. CONSTITUTION:The lower limit value of the voltage or current range of an analog input signal 19 is fixed to a certain lower limit frequency (for example, 50kHz) and the upper limit value is fixed to a certain upper limit frequency (for example, 500kHz) to linearly convert the analog input signal 10 to frequency conversion information 11. In a reception module 2, an analog output signal 14 is unified to the fixed output form independently of the input form of the analog input signal 10 and is taken out by an F-V converter 8 after reception of the optical signal. Thus, a user can freely select the form of an input/output voltage or current.
