Product Description
Industrial-grade isolated converter USB to RS485/RS422 multiple protection circuits support wall-mounted rails

Features:
Using the original imported FT232RNL+SP485EEN chip solution, high-speed communication is stable, reliable and has good compatibility.
On-board integrated power isolation can provide stable isolation voltage, and the isolation terminal does not need additional power supply. Onboard integrated digital isolation can perform signal isolation, with high reliability, strong anti-interference and low power consumption. Onboard TVS (transient voltage suppressor) can effectively suppress surge voltages and transient peak voltages in the circuit, preventing Lightning anti-static
On-board self-restoring fuses and protection diodes ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve impact resistance.
Onboard 15KVESD isolation protection and 600W lightning surge protection
The 120R terminal resistor of the onboard RS485/RS422 interface is enabled by default and can be modified through jumper cap settings.
3 external LED indicators for easy viewing of power supply and signal transceiver status
Industrial rail-type ABS environmentally friendly shell, compact in size, easy to install, and cost-effective
