Toshiba Photoelectric Relay TLP3547 Unboxing and Testing [Copy link]

 I am very happy to receive TLP3547 today. I can't wait to open the package: there is a manual and a small box. The following photo is the small box, which is very delicate and prevents the damage caused by the packing and unpacking of the wild love. The manual explains it very clearly. The 3rd and 4th pins are connected to the excitation, which are divided into three levels: 5V, 12V, and 24V. The common end is at the 5th and 8th pins. The two ends of the resistor connected to the development board are the excitation, and the switch is the common end. Next, use the 5V of the development board to connect to the control end. Use a multimeter to measure the resistance of the common end. It can be heard when the buzzer is turned on. The indication is less than 5 ohms. I think this little thing is good. I didn't add any other power supply, but added a voltage of less than 5V to the control end. It was measured to be about 4.19V, and it can be driven.
