![](/img/devkit/accBoard/USB-TO-4CH-RS485-B/USB-TO-4CH-RS485-B-details-1.jpg)
- 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
