Industrial Isolated USB to 4-ch
RS485 Converter (B)

CH344L | Stable Transmission | Multiple Devices Applicable | Multi-OS Compatible

Features At A Glance

• Adopts original CH344L chip, fast communicating, stable and reliable, better compatibility
• Supports USB to 4-ch isolated RS485, convenient for expanding multiple RS485 industrial serial devices
• Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
• Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection
• Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
• Onboard RS485 output terminal 120R resistors, enabled/disabled via DIP switch
• 10 LEDs for indicating the power, device configuration status and transceiver status
• Industrial grade metal case, supports wall-mount & rail-mount installation, solid and beautiful, easy to install

Specifications

Safer Isolated Design

• Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
• Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption

Multiple Protection, Safe And Stable

Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance.

Multi system Support

Supports Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7, etc.

Transmission Distance Up To 1.2km

The USB Signal Can Be Converted Into 4 Balanced Differential RS485 Signals And The Transmission Rate Is Stable. The Reliable Speed Is 1200~460800bps, The Transmission Distance Is About 1.2km For RS485, And About 5 Meters For USB
