負荷りを動作させる。In FIG. 2, a remote control command signal for operating the load is output from the CPU of the information management center A, and the on signal is input to the remote control command signal transmission device B via the transmission line C to operate the S1 rule. , turns on the contact 11 of the contact circuit 1, operates the X1 loop 22 via the contact 59a of the switching circuit 59 of the remote control relay 5, and the movable contact 59c, thereby forming an on signal input circuit. The contact 22 is activated by the operation of the X relay 22.
-1 is closed and AC power source 7 is input to remote control relay 5 via transformer 3. The AC power supply 7 has a movable contact 55cm, a contact 55b, a diode 51, a relay 57, and a diode 5.
4 - Operate R1 rule 57 in the path of contact 22-1-1 lance 3, connect movable contact 55c and contact 55a, and close contact 56 to supply a predetermined power supply 9 to the load,
Operate the load.

The movable contact 59c and the contact 59b are connected to switch the on signal input circuit to an off signal input circuit (described later). In this state, even if the CPU does not send out the ON signal, the X relay 22 will not be activated by the OFF signal since the contact 59a of the switching circuit 59 and the contact point 59 are open. Therefore, since the AC power source 7 is not supplied to the remote control relay 5, there is no possibility of accidentally stopping the load in operation.

信号待ちの接続状態に復帰する。Next, when the CPU sends one pulse off (iT number), the off signal passes through the transmission line C-+1 and the control command signal transmission device B, closes the contact 12, and contacts the contact 59b, which is the off signal input circuit, and the movable contact. 59c, operate the X relay 22,
By temporarily turning on the contact 22-1, the source 7 is connected to the movable contact 55cm of the remote control relay 5 through the transformer, the contact 55a, the diode 53, the relay diode 52, and the eaves of the contact 22-1. By operating the R relay 57, the multi-contact point 56 is turned off and the load operation is stopped. In this case, the contact 55a and the movable contact 55c are connected, and the contact 59a of the switching circuit 59 and the movable contact 59
c is connected, the state returns to the initial state shown in the figure, and the state returns to the connected state of waiting for an on signal from the CPU.
