Features At A Glance

• Supports USB to 8CH RS485, convenient for expanding multiple RS485 industrial serial devices
• Supports direct power supply via Type-C port, with reserved 5V~36V DC wide voltage screw terminal for auxiliary power input
• Onboard unibody power supply isolation, provides stable isolated voltage
• 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 & anti-electrostatic
• Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
• Built-in 120R terminal resistor on the RS485 ports, configurable via jumper for flexible switching
• LEDs for indicating the power, device configuration status and transceiver status
• Rail-mount case design, support stackable combination, easy to install and safer to use

Safer Isolated Design

• Onboard unibody power supply isolation, provides stable isolated voltage
• 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 Win11/10/8.1/8/7, macOS, Linux, Android, etc.

Transmission distance up to 1.2km

The USB signal can be converted into 8 balanced differential RS485 signals and the transmission rate is stable. The transmission distance is about 1.2km for RS485, and about 5 meters for USB.

Interface Introduction

Note: using USB Type-C port for power supply by default, auxiliary power supply input is optional.

Rail-Mount Support

Supports 35mm standard guide rail, with rail-mount buckle, easy to install.

Supports stackable installation
