Waveshare USB to RS232/485 Industrial Grade Isolated Converter, Onboard Original FT232RNL Chip, Multiple Protection, Wall-Mount and Rail-Mount Support

Onboard original FT232RNL chip. Fast communication, stable and reliable, better compatibility. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal

Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic

Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance

Onboard 120R terminal resistor on the RS485 interface, enabled/disabled via jumper. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption

3 LEDs for indicating the power and transceiver status. Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
