The low level triggers the relay module's power indicator (green) and the 4-way relay status indicator (red). User-friendly interface design, all interfaces can be directly connected through the terminal leads. Four fixing bolt holes are provided.
This is a 2-Bit Bidirectional Voltage Level Translator I2C IIC Level Module CJMCU-0102 TXS0102.This two-bit non-inverting translator can be used to provide digital switching compatibility between mixed-voltage systems because it is a bidirectional voltage
The 2SK1794, 2SK-1794, K1794, 1794 is a 900V 6A 100W TO-3P Package, N-Channel Power MOSFET Switching Transistors With Freewheeling Diode And High Power MOSFET.
The BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.
The 2SC4835, 2SC-4835, 4835 is a 10V 80mA 150mW Silicon NPN Epitaxial Planer Type For UHF Band Low-Noise Amplification Transistor. Manufactured By NEC Semiconductor.
