Provided is a frequency transmitting and receiving device of an automatic block system. In the automatic block system, the frequency transmitting and receiving device according to an embodiment of the present invention includes: a frequency transmitting module which oscillates a specific frequency, transmits the specific frequency to the outside through a surge preventing circuit, and prevents a surge of a voltage inputted from the outside; and a frequency receiving module which receives the frequency, operates a relay by using the frequency through the surge preventing circuit, and prevents the surge of the voltage inputted from the outside. Accordingly, the present invention can continuously transmit or receive the frequency without interruption even though an overvoltage like the surge is generated.
