USB To RS485/422 Industrial Grade Isolated Converter

This USB To RS485/422 converter has an FT232RNL and SP485EEN chip solution that provides stable communication and compatibility with built-in galvanic isolation that makes it lightning-proof and offers anti-electrostatic protection. It offers unibody digital isolation that gives signal isolation, high reliability, strong anti-interference, and low power consumption. Offering stability and safety with its multiple protection, using TVS (Transient Voltage Suppressor) it suppresses surge voltage and transient spike voltage in the circuit, while also being lightning-proof and having ESD protection. 

With a transmission distance of up to 1.2km (Transmission Distance Is About 1.2km For RS485/422 and about 5 Meters For USB) its 32-device support (it is recommended to use repeaters for more than 16 devices) multi-system support (Mac, Linux, Android, WinCE, Win11/10/8.1/8/7 and XP) and a wall and rail mount support, this versatile and easy to install converter is the one you need!

Features

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