control terminals 3B, and the signal output terminals SO₂₁, SO₂₂, SO₂₃, SO₂₄ are provided on the one end side of thecontrol terminals 3B to be adjacent to the remote-controlledrelays control terminals 3B to be adjacent to the remote-controlledttansformer 7. - Moreover, the signal input terminals SO₂₁, SO₂₂, SO₂₃, and SO₂₄ are provided on the same one side where the signal output terminals SO₁₁, SO₁₂, SO₁₃, and SO₁₄ are provided to be close to the side of the remote-controlled
transformer 7. - In the above-structured embodiment, if the monitor signal, which is sent from the
monitor terminals 3A, is input to themain controller 1, the control signal is output from themain controller 1 and input to thecontrol terminals 3B via thetransmission signal line 2. At this time, in thecontrol terminals 3B, thecentral processing unit 20 discriminates whether or not address data, which is included in the control signal input from the transmitting/receivingcircuit 16, coincides with self-address data. If the address data coincides with self-address data, the control signal, which turns on/off the remote-controlledrelays relays control terminals 3B, and turn on/off thelighting equipments 5. - In the above-structured embodiment, the voltage signal, which is output from the remote-controlled
transformer 7, is input to the remote-controlledrelays control terminals 3B. Due to this, the signal line, which transmits the control signal to the remote-controlledrelays control terminals 3B, does not cross the signal line, which supplies power to the remote-controlledrelays transformer 7. - Thereby, the erroneous wiring can be prevented and the wiring can be efficiently provided. Also, electrical interference can be prevented, thereby obtaining the technical advantage in terms of the noise surface.
- Moreover, the
control terminals 3B are arranged between the remote-controlledrelays transformer 7. Due to this, the wiring between thecontrol terminals 3B and the remote-controlledrelays control terminals 3B and the remote-controlledtransformer 7 can be shortened. - Furthermore, in the above embodiment, the signal input terminals SI₂₁, and SI₂₂, which input the voltage signal from the remote-controlled
transformer 7, and the signal output terminal SO₁₁, SO₁₂, SO₁₃, SO₁₄, which output the control signal to the remote-controlledrelays relays control terminals 3B are opposed to each other. Moreover, the signal input terminals SI₂₁, and SI₂₂ are arranged on the side of the remote-controlledtransformer 7. The signal output terminals SO₁₁, SO₁₂, SO₁₃, and SO₁₄, and the signal output terminals SO₂₁, SO₂₂, SO₂₃, and SO₂₄ are provided on the side of the remote-controlledrelays transformer 7 to thecontrol terminals 3B, can be shortened. - Fig. 9 is a view showing a modification of the
control terminal 3B. As shown in Fig. 9, on one side of thecontrol terminals 3B and the same one side where the signal input terminals 6A11 to 6S14 of the remote-controlledrelays relays relays control terminals 3B to be adjacent to the remote-controlledtransformer 7. The first and second signal output terminals So₁₁, SO₁₂, SO₁₃, SO₁₄, SO₂₁, SO₂₂, SO₂₃, SO₂₄ are provided on the other end dise of thecontrol terminals 3B to be adjacent to the remote-controlledrelays - According to the above structure, similar to the above-mentnioned embodiment, the erroneous wiring can be prevented. Moreover, the wiring between the
control terminals 3B and the remote-controlledrelays control terminals 3B and the remote-controlledtransformer 7 can be shortened. - Additionally, the present invention is not limited to the above-mentioned embodiment. Various modifications can be applied to the present invention without departing from the gist of the present invention.
