The PWM transfer voltage module LC-LM358-PWM2V converts the PWM digital signals into 0 to 10V analog signals. It can be used as signal interface switching for PLC or other industrial control boards.
The CD4066BM is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin-for-pin compatible with the CD4016B device, but exhibits a much lower on-state resistance.
This relay module is 5V active low. It is a single channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.
S9015 PNP Transistor: Low Frequency, Low Noise TO-92 S9015 Equivalents and Circuit, S9015 is a well-known PNP silicon BJT transistor. This transistor is mainly designed for low gain signal amplification.
This XL4015-based voltage converter is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module with Constant Voltage and Constant Current control, capable of driving a 5A load with high efficiency, low ripple, and excellent line and load regulation.
