제1도는 종래 반복 타이머의 회로도로서 그 구성을 설명하면 다음과 같다.1 is a circuit diagram of a conventional repetition timer.
전원입력단자(②,⑦)에 접속된 트랜스(TRS)의 2차측에 브리지다이오드(BD), 콘덴서(C11)를 접속하고, 정류된 전압단이 저항(R13), 다이오드(D12)를 통해 시간지연회로(IC1)로 접속됨과 아울러 저항(R11)을 통해 발광다이오드(L11)에 접속되며, 상기 시간지연회로(IC1)의 출력단에는 트랜지스터(T11)이 결합되고 그 콜렉터가 저항 (R12)를 통해 트랜지스터(T13)의 베이스와 연결된다.The bridge diode BD and the capacitor C 11 are connected to the secondary side of the transformer TRS connected to the power input terminals ② and ⑦, and the rectified voltage terminals are the resistor R 13 and the diode D 12 . It is connected to the time delay circuit (IC 1 ) through and connected to the light emitting diode (L 11 ) through the resistor (R 11 ), the transistor T11 is coupled to the output terminal of the time delay circuit (IC 1 ) and its collector Is coupled to the base of transistor T13 via resistor R 12 .
그리고 상기 트랜지스터(T13)의 콜렉터에는 릴레이(Ry)가 결합됨과 아울러 저항(R15)과 다이오드(D13) 및 발광다이오드(L12)를 통해 시간지연회로(IC2)에 연결되며, 상기 시간지연회로(IC2)의 출력측에는 트랜지스터(T12)가 접속되고 그 콜렉터가 상기 시간지연회로(IC1)의 전원단으로 접속된다.In addition, a relay Ry is coupled to the collector of the transistor T13 and is connected to a time delay circuit IC2 through a resistor R 15 , a diode D 13 , and a light emitting diode L 12 . The transistor T12 is connected to the output side of the circuit IC2, and its collector is connected to the power supply terminal of the time delay circuit IC1.
상기와 같은 구성을 갖는 종래의 타이머 회로에 대하여 그 동작과 문제점을 상세히 설명하면 다음과 같다.The operation and problems of the conventional timer circuit having the above configuration will be described in detail as follows.
전원입력단자(②,⑦)에 전원을 인가하면 트랜스(TRS)를 통해 전압이 강하된 후 브리지다이오드(BD), 콘덴서(C11)를 통해 직류전원이 발생되며, 이 직류전원은 저항(R13), 다이오드(D12)를 통해 시간지연회로(IC1)의 전원단자(VDD)에 공급되어 상기 회로(IC1)를 구동시킴과 아울러 저항(R11)을 통해 발광다이오드(L11)를 턴온시킨다.When power is applied to the power input terminals (②, ⑦), the voltage drops through the transformer (TRS), and then DC power is generated through the bridge diode (BD) and the capacitor (C 11 ). 13, the diode is supplied to the power supply terminal (V DD) of a time delay circuit (IC 1) through D 12) through said circuit (IC 1) for driving Sikkim as well as a resistance (R 11), a light emitting diode (L 11 Turn on).
이때, 상기 시간지연회로(IC1)는 전원(VDD)이 인가된 뒤에 일정시간동안 그의 출력(OUT)이 저전위를 유지하여 트랜지스터(T11)를 오프시킴으로서 저항(R12)을 통해 트랜지스터(T13)의 베이스측에 고전위를 인가하여 상기 트랜지스터(T13)을 오프시킨다.In this case, the time delay circuit (IC 1) is a transistor with a power supply (V DD) is applied to a certain amount of time its output (OUT) is sikimeuroseo resistance (R 12) to maintain a low potential turns off the transistor (T 11) for the back A high potential is applied to the base side of T13 to turn off the transistor T13.
따라서, 직류전원의 공급이 차단되어 릴레이(Ry)와 시간지연회로(IC2)는 동작되지 않게 된다.Therefore, the supply of the DC power is cut off so that the relay Ry and the time delay circuit IC 2 do not operate.
이러한 상태로 일정시간이 경과하면 시간지연회로(IC1)는 그 출력단(OUT)으로 고전위의 신호를 출력하여 트랜지스터(T11,T13)를 연속으로 온시키고 트랜지스터(T13)를 통과한 직류전원에 의해 릴레이(Ry)를 구동시킴과 아울러 저항(R16), 다이오드(D13)를 통해 발광다이오드(L12)를 온시키고 시간지연회로(IC2)를 구동시킨다.After a certain time has elapsed in this state, the time delay circuit IC 1 outputs a high potential signal to the output terminal OUT to continuously turn on the transistors T 11 and T 13 and pass through the transistor T 13 . In addition to driving the relay Ry by a DC power supply, the light emitting diode L 12 is turned on through the resistor R 16 and the diode D 13 , and the time delay circuit IC 2 is driven.
이때, 일정시간에 도달하면 시간지연회로(IC2)의 출력(OUT)이 고전위로 되어 트랜지스터(T12)를 온시킴으로서 시간지연회로(IC1)의 전원공급을 차단함과 아울러 트랜지스터(T13)를 오프시킴에 따라 시간지연회로(IC2)와 릴레이(Ry)는 차단상태로 된다. 이와 같이 트랜지스터(T11∼T13)를 이용하여 시간지연회로(IC1,IC2), 릴레이(Ry)를 온,오프하는 것을 반복한다.At this time, when a certain time is reached, the output OUT of the time delay circuit IC 2 becomes a high potential, thereby turning on the transistor T 12 to cut off the power supply of the time delay circuit IC 1 and to the transistor T 13. ), The time delay circuit IC 2 and the relay Ry are cut off. As described above, the time delay circuits IC 1 and IC 2 and the relay Ry are turned on and off using the transistors T 11 to T 13 .
그러나, 이러한 종래의 반복 타이머회로는 트랜스를 사용하므로 제품의 중량이 무거울 뿐 아니라 부피가 크게 되며, 트랜지스터의 스위칭 작용으로 전원을 제어하므로 큰 정격의 릴레이 구동이 어렵게 될 뿐 아니라 교류용 릴레이 구동을 할 수 없게 되는 문제점이 있었다.However, since the conventional repetitive timer circuit uses a transformer, the weight of the product is not only heavy, but also bulky, and since the power is controlled by the switching action of the transistor, it is not only difficult to drive a large rated relay but also to perform an AC relay drive. There was a problem that became impossible.
본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위해서 큰 정격의 릴레이 구동과 교류 및 직류용 릴레이의 구동을 가능하게하며 트랜스를 제거하여 중량 및 부피를 가볍게 할 뿐 아니라 염가의 제품을 공급하도록 한 반복 타이머 회로를 안출한 것으로, 이하 첨부한 도면에 의해 상세히 설명한다.The purpose of the present invention is to solve the conventional problems as described above to enable the operation of large rated relay drive and the relay for alternating current and direct current, and to reduce the weight and volume by eliminating the transformer to supply inexpensive products. One repetition timer circuit is devised, which will be described in detail with reference to the accompanying drawings.
제2도는 본 고안 반복 타이머의 회로도로서 이에 도시한 바와 같이, 전원입력단자(②)의 전원이 직렬로 된 릴레이(Ry), 다이오드(D3), 저항(R3), 발광다이오드(D4)를 통해 시간지연회로(IC1)의 전원축(VDD)에 인가함과 아울러 직렬로 된 저항(R1,R4), 다이오드(D2)를 통해 시간지연회로(IC2)의 전원측(VDD)에 인가한다.FIG. 2 is a circuit diagram of a repetitive timer of the present invention, as shown in FIG. 2, in which the power of the power input terminal ② is in series with a relay Ry, a diode D 3 , a resistor R 3 , and a light emitting diode D 4. ) via a time delay circuit (the resistance as well as in series and also applied to the power axis (V DD) of the IC 1) (R 1, R 4), diode (D 2), the power supply side of the time delay circuit (IC 2) through Is applied to (V DD ).
그리고 상기 다이오드(D1,D3)의 애노우드측 양단에 콘덴서(C1)를 접속하여 전위의 불균형 상태로 만들고, 상기 다이오드(D3,D1)의 애노우드측, 릴레이(Ry), 저항(R1), 콘덴서(C1)의 일측과 시간지연회로(IC1,IC2)의 그라운드(GND)측 사이에 실리콘 제어 정류기(SCR1,SCR2)를 접속하여 시간지연회로(IC1,IC2)의 출력(OUT)으로 게이트측을 제어하게 하며, 상기 시간지연회로(IC1,IC2)의 그라운드(GND)와 전원입력단자(②)사이에 직렬로 다이오드(D6), 저항(R2)을 접속하여 역기전력을 방지함과 아울러 다이오드(D6)를 통해 전원입력단자(⑦)에 접속하여 구성한다.And the diodes (D 1, D 3) anode connected to a capacitor (C 1) on the side of both ends to create a unbalanced state of the potential, the anode side, a relay (Ry) of the diode (D 3, D 1) of, The time delay circuit IC is connected by connecting the silicon controlled rectifiers SCR 1 and SCR 2 between the resistor R 1 and one side of the capacitor C 1 and the ground GND side of the time delay circuits IC 1 and IC 2 . 1 , IC 2 ) to control the gate side, and the diode (D 6 ) in series between the ground (GND) and the power input terminal (②) of the time delay circuit (IC 1 , IC 2 ). In addition, the resistor R 2 is connected to prevent back electromotive force and is connected to the power input terminal ⑦ through the diode D 6 .
한편, 제3a도 내지 제3d도는 본 고안 반복 타이머의 구동에 따른 파형도로서 이에 도시한 바와 같이, 제3a도는 전원입력단자(②,⑦)의 전원파형, 제3b도는 시간지연회로 (IC1)의 출력파형, 제3c도는 시간지연회로(IC2)의 출력파형, 제3d도는 릴레이(Ry)의 출력파형이고, t1,t2는 지연시간을 나타낸 것이다.3A to 3D are waveform diagrams of driving the repetitive timer of the present invention. As shown in FIG. 3A, power waveforms of power input terminals ② and ⑦ are shown, and FIG. 3b is a time delay circuit IC 1. Figure 3c is the output waveform of the time delay circuit (IC 2 ), Figure 3d is the output waveform of the relay Ry, t 1 , t 2 represents the delay time.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
전원입력단자(②,⑦)에 제3a도에 도시한 바와 같은 전원을 인가하면 릴레이(Ry), 저항(R1)에 의해 콘덴서(C1)의 양단에는 전위의 불균형이 발생됨에 따라 다이오드(D3), 저항(R3)을 통해 인가되는 전원에 의해 발광다이오드(D4)를 점등됨과 아울러 시간지연회로(IC1)의 단자(VDD)에 전원이 공급되어 상기 시간지연회로(IC1)가 동작된다.When a power source as shown in FIG. 3a is applied to the power input terminals ② and ⑦, an unbalance of potential is generated at both ends of the capacitor C 1 by the relay Ry and the resistor R 1 . D 3 ), the light emitting diode D 4 is turned on by the power applied through the resistor R 3 , and the power is supplied to the terminal V DD of the time delay circuit IC 1 so that the time delay circuit IC 1 ) is operated.
이렇게 일정시간이 경과하면 상기 시간지연회로(IC1)의 출력(OUT)이 일정시간(t1)동안 고전위로 되어 실리콘제어정류기(SCR1)를 온시킴에 따라 릴레이(Ry)가 제3d도에 도시한 바와 같이 구동되며 이때 상기 제3d도에서 릴레이(Ry)가 구동되는 구간에는 신호를 로우로 표시하였다.When a predetermined time elapses, the output Ry of the time delay circuit IC 1 becomes a high potential for a predetermined time t1 to turn on the silicon-controlled rectifier SCR 1 , so that the relay Ry is connected to FIG. 3d. As shown in FIG. 3, the signal is displayed low in the section in which the relay Ry is driven in FIG.
실리콘제어정류기(SCR1)의 애노우드전압이 낮아지게 됨에 따라서 콘덴서(C1)은 반대로 충전이 되고 이에 따라 저항(R1)에 인가된 전원이 다이오드(D1), 저항(R4)을 통해 발광다이오드(D2)를 온시킨 후 시간지연회로(IC1)의 단자(VDD)에 전원을 공급하여 제3c도에 도시한 바와 같이 시간(t2)을 지연한다.As the anode voltage of the silicon controlled rectifier SCR 1 is lowered, the capacitor C 1 is charged in reverse, so that the power applied to the resistor R 1 is applied to the diode D 1 and the resistor R 4 . After turning on the light emitting diode D 2 , power is supplied to the terminal V DD of the time delay circuit IC 1 to delay the time t 2 as shown in FIG. 3C.
이때, 일정 시간이 지나면 시간지연회로(IC2)의 출력(OUT)이 고전위로 되어 실리콘제어정류기(SCR2)를 온시킴에 따라 실리콘제어정류기(SCR1)의 애노우드측이 고전위로 되어 시간지연회로(IC1)의 단자(VDD)에 정격 전압을 인가한다.At this time, when a certain time passes, the output OUT of the time delay circuit IC 2 becomes a high potential and the silicon controlled rectifier SCR 2 is turned on, so that the anode side of the silicon controlled rectifier SCR 1 becomes a high potential. The rated voltage is applied to the terminal V DD of the delay circuit IC 1 .
이와 같이 콘덴서(C1)를 통해 실리콘제어정류기(SCR1,SCR2)의 온, 오프를 반복하여 릴레이(Ry)를 구동 차단한다.As described above, the relay Ry is driven off by repeatedly turning on and off the silicon controlled rectifiers SCR 1 and SCR 2 through the capacitor C 1 .
이상에서 상세히 설명한 바와 같이 본 고안은 실리콘제어정류기와 콘덴서를 이용하여 릴레이 및 시간지연회로의 전원을 차단 및 구동할 수 있게 되므로 공장자동화 설비 및 시퀀스 제어회로 장치에 시간을 제어하는데 사용되며, 특히 보일러등의 전원인가시간 및 전원차단시간을 주기적으로 반복하여 설비의 효율을 높일 수 있다.As described in detail above, the present invention can be used to control the time in the factory automation equipment and the sequence control circuit device because it can cut off and drive the power of the relay and the time delay circuit using the silicon controlled rectifier and the condenser. It is possible to increase the efficiency of the facility by periodically repeating the power-on time and the power-off time.
