In the same manner as described above, the extended function modules 5a can be stably fixed. 1 to 3, the extended function module 5 is connected to only one side of the basic function module 4, but the extended function module 5 may be connected to both sides of the basic function module 4. However, the number of extended function modules 5 that can be connected to the basic function module 4 is limited by the power supply capability of the AC / AC converter 43a.

  In addition, when the number of extended function modules 5 to be connected increases, the plate frame 80 is deformed by the weight of the extended function module 5, and the end of the plate frame 80 (for example, the side opposite to the side fixed to the mounting frame 70).

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. It is possible to easily cope with expansion of functions by connecting and using.

  As a method for transmitting information signals, either baseband transmission or broadband transmission may be adopted, and any protocol may be used.
