User Manual / Datasheet / Example Codes Etc.

• Adopts original CH344L chip, high-speed communication, stable and reliable, better compatibility.
• Onboard unibody power isolation, provides stable isolation voltage, no additional power supply is required at the isolated side.
• Onboard unibody digital isolation, support signal isolation, with better reliability, stronger anti-interference ability, and lower power consumption.
• Onboard TVS (Transient Voltage Suppressor) to effectively suppress surge voltage and transient spike voltage in circuits, lightning-proof protection, and anti-static protection.
• Onboard self-resetting fuses and protection diodes ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve shock resistance.
• Built-in RS485 output terminal 120R, can be enabled by dip switches, and flexible switching.
• 10x external LEDs for power, device configuration status, and signaling status.
• Industrial grade metal case, support wall-mount and rail-mount installation, rigid and nice-looking, easy to install.
