Description
본 고안은 PLC(Programmable Logic Controller)의 입출력장치에 관한 것으로서, 특히 PCB(Printed Circuit Board)회로기판과 입출력 표시부가 착탈 가능하도록 한 입출력장치에 관한 것이다.The present invention relates to an input / output device of a programmable logic controller (PLC), and more particularly, to an input / output device in which a printed circuit board (PCB) circuit board and an input / output display unit are detachable.
도 1a 내지 1b는 일반적인 피엘씨의 입출력장치를 나타낸 측면도 및 평면도이다.1A to 1B are a side view and a plan view of a general PLC input / output device.
도 1a를 참조하면, 일반적인 PLC의 입출력장치는 PCB회로기판(10)과 입출력 표시부(12)을 콘넥터(11)로 고정시켜놓은 구조로 구성된다.Referring to FIG. 1A, a general PLC input / output device has a structure in which a PCB circuit board 10 and an input / output display unit 12 are fixed by a connector 11.
여기서, 입출력 표시부(12)는 도1b에 나타낸 바와 같이 사용자에게 입출력 상태를 알려주는 복수개의 LED(Light Emitting Diode)(0~F)로 구성된다.Here, the input / output display unit 12 is composed of a plurality of LEDs (Light Emitting Diodes) 0 to F which inform the user of the input / output state as shown in FIG. 1B.
이와 같이 구성된 피엘씨의 입출력장치의 동작을 설명하면 다음과 같다.The operation of the input and output device of the PLC configured as described above is as follows.
도2에 나타낸 바와 같이 입출력 콘트롤러부(13)에서 0또는 1를 출력하면 접점출력 회로부(14)에서 출력을 하고 이에 대한 상태를 입출력 표시부(12)에 표시하게 된다.As shown in FIG. 2, when the input / output controller unit 13 outputs 0 or 1, the contact output circuit unit 14 outputs the state, and the state thereof is displayed on the input / output display unit 12.
여기서, 1일 경우에는 입출력 표시부(12)에 LED가 오프되어 도1b에 나타낸 바와 같이 1~ F LED처럼 점멸된 상태가 된다.Here, in the case of 1, the LED is turned off in the input / output display unit 12, and as shown in FIG.
또한, 0일 경우에는 입출력 표시부(12)에 LED가 온되어 도1b에 나타낸 바와 같 이 0번 LED처럼 점등되어 출력접점이 연결되었음을 표시하게 된다.In addition, in the case of 0, the LED is turned on in the input / output display unit 12, and as shown in FIG. 1B, the LED is turned on to indicate that the output contact is connected.
즉, 도2에 나타낸 바와 같이 입출력 콘트롤러부(13)에서 1이 출력되면 포인트 A부분이 하이(Hign)상태가 되어 LED가 점멸되고 0이 출력되면 포인트 A부분이 로우(LOW) 상태가 되어 +5V에서 전원이 공급되어 LED가 점등되어 출력상태를 표시하게 된다.That is, as shown in FIG. 2, when 1 is output from the input / output controller unit 13, the point A portion becomes high and the LED blinks, and when 0 is output, the point A portion becomes low. Power is supplied at 5V and LED turns on to indicate output status.
이와 같은 종래기술에 따른 피엘씨의 입출력장치는 PCB회로기판과 입출력 표시부가 콘넥터에 납땜으로 고정되어 있으므로 필요에 따라 착탈 불가능한 문제점이 있다. 또한, 각 입출력 모듈 마다 입출력 표시부를 고정시켜 둠으로써 입출력 모듈 이상의 입출력 표시부가 필요하게 되어 불필요한 원가를 상승시키는 문제점이 있다.PLC's input and output device according to the prior art is a PCB circuit board and the input and output display is fixed to the connector by soldering, there is a problem that can not be removed as needed. In addition, since the input / output display unit is fixed to each input / output module, the input / output display unit beyond the input / output module is required, resulting in an unnecessary cost increase.
또한, 캐비넷 속에 또는 기계장치내에 부착되기 때문에 캐비넷이나 기계장치 외부에서는 입출력 모듈의 입출력 표시부를 직접 확인해볼 수 없는 경우가 많으므로 실제 시험운전외에는 별로 유용하게 사용되지 못하는 문제점이 있다.In addition, since it is attached to the cabinet or in the mechanical device, the input / output display part of the input / output module cannot be directly checked in the cabinet or the outside of the mechanical device.
본 고안은 이와 같은 종래기술에 따른 피엘씨의 입출력장치의 제반 문제점을 해결하기 위하여 안출한 것으로서, 본 고안에 따른 목적은 PCB회로기판과 입출력 표시부를 납땜으로 고정시키지 않고 콘넥터를 통하여 착탈이 가능하도록한 피엘씨의 입출력장치를 제공함에 있다.The present invention was devised to solve all the problems of the input and output device of the PLC according to the prior art, the object according to the present invention is to be detachable through the connector without fixing the PCB circuit board and the input and output display by soldering. It is to provide an input and output device of a PL.
