1. Triac 출력에 전력부족이 예상되어 SST Module을 추가부착할 경우 SSR 전원이 계속 ON 되어 있다. 이럴경우 그림의 회로와 같이 TRIAC 드라이버 회로에서 C21 을 제거하고 연결하면 문제가 해결될수 있습니다.

1. NE555 타이머 사용한 비안정멀티바이브레이터 ① 발진주기 : T=0.7(R1 + 2R2)C ② 회로 ③ 콘덴서 C가 저항( R1 + R2 )을 거쳐 충전할 동안 출력 단자 3번 핀에서 "H"레벨의 신호가 출력되 고 콘덴서 C가 저항 R2을 통해 방전할 동안은 "L"레벨의 신호가 출력된다. ④ NE555의 5번 핀(제어 전압 ..

Figure 1: Circuit Diagram of Isolated RS485 Interface Figure 1 shows the circuit diagram of RS485 interface. Connector K1 is linked to the serial port of the PC, power to the PC side of the circuit is derived from the signal lines DTR and RTS. Positive supply is derived from RTS and negative supply from the DTR line. The RTS line is also used to control the data direction of RS485 driver IC U4...

Here is simple a circuit for a MOSFET used as a switch. The diode is needed if the load is inductive. The diode protects the MOSFET from high voltage back emf pulses by allowing the load current to die away gradually. Drive a MOSFET from a PIC Chip If 5V is applied to the input above, some MOSFETS would not turn fully on (saturate) so they would not act correctly as a switch. Here is a circuit ..
