Power Supply Isolated Module High Speed USB to TTL Serial Port Optocoupler Isolated TTL Output Modul

Feature: 1. Safety Isolation: Strong current devices, such as inverters connected to the computer may burn USB, our TTL output module can isolate the computer USB port, the motherboard and safety, can effectively prevent the USB port damage, resulting in human injury. 2. Optocoupler Isolation: This TTL output module has serial port TTL level optocoupler isolation with fast speed up to 256000bps and high reliability. 3. On Board Chip and Module: On board stable CH340T USB to serial chip, on board 500mA self recovery fuse and 5V isolated power module for protecting the computer from damage. 4. Prevent Interference: Strong interference electrical equipment such as drivers, inverters can generate interference leading to computer failure, this isolated output module can isolate the USB interface for communication to prevent interference with the computer. 5. Sensitive Equipment Transmission: The computer itself is also a source of noise, by isolating the USB port, it can prevent high frequency interference from the computer from being transmitted to sensitive equipment for better data acquisition, such as measurement equipment and other equipment. Specification: Item Type: TTL Output Module Material: Electronic components On Board Chip: On board stable CH340T USB to serial chip On Board Module: On board 500mA self recovery fuse and 5V isolated power supply module protecting the computer from damage Optocoupler Isolation: Serial port TTL level optocoupler isolation, fast speed (up to 256000bps), high reliability Protection Diode: Output TX RX side with protection diode function, can improve the shock resistance Electrical Isolation: PC USB side and serial port output side to achieve complete electrical isolation Output Level: Output TTL level can be set to 3.3V 5V Output Current: Maximum output current 150mA for serial output Package List: 1 x TTL Output Module Note: As there is a certain error in the 5V to 5V isolated power supply on the isolated serial module, the output power supply voltage will be around 5.4V when VCC is connected to the 5V pin through the jumper cover at no load, but don't worry, the output voltage will automatically drop to around 5V when connected to the user's device.
