Description
CH344L | Stable Transmission | Multi-device Applicable | Multi-system Compatibility
- Adopts original CH344L chip, fast communication, stable and reliable, better compatibility
- Supports isolated USB to 4-ch RS485 conversion, convenient for expanding multiple industrial RS485 serial devices
- Onboard unibody power isolation, provides stable isolated voltage, no extra power supply needed 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 suppresses surge voltage and transient spike voltage in the circuit, anti-lighting & anti-static
- Onboard self-recovery fuse and protection diodes, ensures stable current/voltage outputs, provides over-current/over-voltage proof, improves shock resistance
- Onboard 120R terminating resistors for RS485 output terminals, enabled/disabled by DIP switch
- 10x LED indicators for power, device status and transceiver status
- Industrial grade metal casing, supports wall-mount and DIN-rail mounting, solid and durable, easy to install
| PRODUCT TYPE | Industrial Isolated USB to RS485 Converter | |
|---|---|---|
| HOST PORT | USB | |
| DEVICE PORT | RS485 | |
| BAUDRATE | 1200bps ~ 460800bps | |
| USB | Operating voltage | 5V |
| Connector | USB-B | |
| Protection | 500mA self-recovery fuse, output isolation | |
| ISOLATED RS485 | Connector | Screw terminal |
| Direction control | Hardware automatic control | |
| Protection | 600W lightningproof and surge-suppress, 15KV ESD protection (onboard 120R matching resistors) | |
| Transmission mode | Point-to-multipoints (up to 32 nodes, it is recommended to use repeaters for 16 nodes or more) | |
| INDICATORS | PWR | Power indicator, glows when USB is connected and voltage is detected |
| ACT | Status indicator, glows green when driver is detected | |
| RXD | RXD indicator, glows when device ports are sending data back | |
| TXD | TXD indicator, glows when USB port is sending data | |
| OPERATING ENVIRONMENT | Temperature | -40 ~ 85℃ |
| Humidity | 5%RH ~ 95%RH | |
| OPERATING SYSTEM | Win7/8/8.1/10/11, Mac, Linux, Android | |
- Onboard unibody power isolation, provides stable isolated voltage, no extra power supply needed 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 suppresses surge voltage and transient spike voltage in the circuit, anti-lighting & anti-static. Onboard self-recovery fuse and protection diodes, ensures stable current/voltage outputs, provides over-current/over-voltage proof, improves shock resistance.
Supports Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7 etc.
The USB signal can be converted into 4 balanced differential RS485 signals with a stable rate. The reliable rate is 1200~460800bps, the transmission distance is about 1.2km for RS485 and about 5 meters for USB.
Aluminum alloy enclosure with sandblasting and anodic oxidation process.
Solid and durable, stylish appearance and nice touch feeling.
Supports wall-mount & DIN-rail mounting, more flexible for industrial installation.
