Waveshare Industrial Isolated USB To 4-Ch RS485 Converter (B), CH344L Chip, Multi Protection Circuits, Multi Systems Support

USB TO 4CH RS485 (B) is an industrial USB to RS485 converter, adopting original CH344L, with protection circuits such as built-in power isolation, ADI magnetical isolation, and TVS, aluminum alloy case design. USB TO 4CH RS485 (B) is easy to operate, automatic transmit, featuring fast communication, stability, reliability, and safety, suitable for industrial devices and applications with high requirements.

Features:

1. Adopts original CH344L chip, high-speed communication, stable and reliable, better compatibility.
2. Onboard unibody power isolation, provides stable isolation voltage, no additional power supply is required at the isolated side.
3. Onboard unibody digital isolation, support signal isolation, with better reliability, stronger anti-interference ability, and lower power consumption.
4. Onboard TVS (Transient Voltage Suppressor) to effectively suppress surge voltage and transient spike voltage in circuits, lightning-proof protection, and anti-static protection.
5. Onboard self-resetting fuses and protection diodes ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve shock resistance.
6. Built-in RS485 output terminal 120R, can be enabled by dip switches, and flexible switching.
7. 10x external LEDs for power, device configuration status, and signaling status.
8. Industrial grade metal case, support wall-mount and rail-mount installation, rigid and nice-looking, easy to install.
