Overview

• USB TO RS485/422, an industrial-grade USB to RS485/422 isolated converter, adopts the original FT232RNL, an industrial rail case design, built-in protection circuits such as power isolation, ADI magnetic coupling isolation, and TVS. USB TO RS485/422 is easy to operate, and can automatically transmit and receive without delay. It features fast communication speed, stability, reliability, and safety, which can be applied to various industrial control devices or applications with high communication requirements.

   Features

• Onboard Original FT232RL and SP485EEN chip. Fast communication, stable and reliable, better compatibility.
• Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal.
• Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, and low power consumption.
• Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic.
• Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock resistance.
• Onboard 15KV ESD isolation protection and 600W lightning-proof & anti-surge protection.
• Onboard 120R terminal resistor on the RS485/RS422 ports, enable by default, configurable by jumper.
• 3x LEDs for indicating the power and transceiver status.
• Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
