The shape of the magnetic coupling portion X and the transparent portion Y of the basic function module 4 and the distance between them may be combined with those of the connection ports 22 and 32 to form a shape.

  In the above embodiment, since the information path and the power path are separated, the power line L1 and the information line L2 are connected to the gate device 1 respectively. However, if the information signal is transmitted by the power line carrier, the power path Can also be used as the information path, so that only the power line L1 can be used for wiring, and wiring construction can be simplified. That is, the preceding wiring in each switch box 90 is only the power line L1, correspondingly, the terminal portions 31a and 31b and the information path connection port 32 of the gate device 1 are eliminated, and only the terminal portions 21a and 21b and the power path connection port 22 are provided.

Then, the information signal received via the PLC modem unit 45a is transmitted as an optical signal by the E / O conversion unit 46a, and the information signal composed of the optical signal received by the O / E conversion unit 46b is transmitted to the PLC modem unit 45a. Is transmitted by power line carrier. In addition, the transmission / reception unit 45 outputs an information signal received via the PLC modem unit 45a to the arithmetic processing unit 26, causes the arithmetic processing unit 26 to perform data processing, and an information signal input from the arithmetic processing unit 26 Is transmitted from the PLC modem unit 45a to the power line L1 via the power connector 2 by power line conveyance.

  Note that the power line carrier modulation scheme employed in the PLC modem unit 45a may be any of various schemes such as a broadband spread spectrum scheme, a multicarrier scheme, and an OFDM scheme, and is not specifically described here. In the example shown in FIG. 7, the information signal transmitted by the power line carrier communication is separated by the PLC modem unit 45a of the basic function module 4, and the E / O conversion unit 46a and the O / E conversion between the function modules 4 and 5 are separated. Although information signals are exchanged using the unit 46b, a PLC modem unit may be provided in each functional module 5 so that each functional module 5 exchanges information signals by power line carrier communication.

  In this embodiment, the extended function module 5 receives power supply and exchanges information signals via the basic function module 4, and secures both the power path and the information path in the extended function module 5. Depending on the function of the extended function module 5, only one of power supply and information signal transmission / reception may be performed to secure either the power path or the information path. By connecting and using, it is possible to easily cope with expansion of functions.
