This device provides only control the correctness of the entered information in the selected triggers. The purpose of the invention is to create a device that continuous control of the operation of the power relay switch. The proposed device control relay is on switch uses the difference of times of switching of the actuating relay switch (unit MS) and trigger memory command relay control (less than one ISS). For continuous control of the power relay switch requires a separate change-over contacts in the Executive relay. Device for continuous control of the power relay switch containing a group of triggers memory management commands relay information highway, bus recording information bus installation the relay switch to its original state, with each bus information bus connected to the input D of the corresponding trigger memory command control relays, bus recording information connected to the input C of each trigger memory command relay control, tire installation of the relay switch to its original state is connected to the input R of each trigger memory command control relay, characterized in that it introduced the control change-over contact group b in the Executive relay switch, extender pulse width, logic item 2I-NOT, trigger, remember the case of a malfunction of the switch, the logical element AND-NOT, and the inverted output of the trigger memory control commands of the relay is connected to the input of the amplifier relay and the normally closed contact of the control relay contact b, direct trigger memory control commands of the relay is connected to the normal is but open contact of the control relay contact b, the output of the amplifier control relay is connected to the first output winding of the control relay, the second terminal of the control winding of the relay is connected to a common bus, each relay output control relay contact b is connected to a separate input of the logical element AND-NOT, and the number of inputs of the logical element AND-NOT must match the number of the actuating relay switch covered by the control bus write information connected to the inputs C of the flip-flop memory command, control relays and direct input expander pulse width, tire installation of the relay switch to its original state is connected to the input R of each trigger memory management commands the relay to trigger memory in case of invalid operation switch and to the inverted input of the expander pulse, the outputs of the logical element AND-NOT and extender pulse is connected to the inputs of the logic element 2I, the output of which is connected to the input S of the flip-flop remember the case of a malfunction of the switch, the signal failure of the power relay switch is removed from the trigger output memorizing the case of a malfunction of the switch. The figure presents a structural diagram of a device for continuous control of the power relay com is otatara. The figure shows: 1 - trigger memory command control relay; 2 - power control relay; 3 - relay, Executive a and control b groups of switching contacts; 4 - information highway; 5 - bus recording information in the trigger. 6 - bus installation the relay switch to its original state; 7 - extender pulse duration; 8 is a logical element 2I-NO; 9 is a trigger to remember the case of a malfunction of the power relay switch; 10 is a logical element AND - NOT. The control device operates as follows. Information install the power relay switch in brand new condition comes on highway 4. According to the recording signal in the bus 5 trigger remember commands to control the relays 1 and translate the Executive relay 3 switch in the state corresponding to the received information. Between changes of state of the switch at the correct functioning of the amplifier 2 and relay 3, regardless of the state of the trigger memory command 1, the inputs of the logical element AND-NOT 10 receives the logical unit. The signal of the logic zero from the output of element AND-NOT 10 prohibits the entry of the logical units in the trigger memory in case of invalid operation switch 9. When the mismatch state relay 3 state of sootvetstvuyuschego trigger 1, caused by failure relay 3 or amplifier 2, a logical zero with the switching output of the control group relay 3b will arrive at the input of the logical element AND-NOT 10 and brings the release of the latest in state of the logical unit.

When authorized to change the state of the power relay switch signal received on the bus track 5, starts the pulse extender 7. A logic low at the output of the pulse extender 7 blocks passage of a signal of failure of the switch via the logical element 2I-8 on the actuation time of the relay 3, which change their state according to the recording signal. Obviously, to avoid passing false signal rejection in the process authorized changes the state of the power relay switch it is necessary that the duration of the pulse produced by the pulse extender 7 exceeded the maximum switching time of the relay 3, used in multi-relay switch. Similarly, the operation of the elements of the device control setting signal relay switch to its original state A state change trigger memory management team relay 1 when there is no signal records in the bus 5, for example from interference will cause the switching time relay 3 the emergence of a low logic level on the corresponding input of the logical element AND-NOT 10 and will produce a record of the logical units in the trigger memory in case of invalid operation switch 9.
