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
