Adopts original FT232RNL and SP485EEN chip solution, provides stable communication with built-in galvanic isolation, lightning proof, and anti-electrostatic protection, and so on, it is an ideal choice for industrial control equipment and/or applications with high communication requirements.
Features at a Glance
- Onboard Original FT232RL and SP485EEN chip. Fast communication, stable and reliable, better compatibility
- Onboard unibody power supply isolation, provides stable isolated voltage and 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 suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
- Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock resistance
- Onboard 15KV ESD isolation protection and 600W lightning proof & anti-surge protection
- Onboard 120R terminal resistor on the RS485/RS422 ports enable by default, configurable by jumper
- 3 LEDs for indicating the power and transceiver status
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective

Onboard Original Chips
Onboard Original FT232RL And SP485EEN Chips, Providing Better Stability And Compatibility
Galvanic Isolated Design
Onboard unibody power supply isolation, provides stable isolated voltage and 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 suppresses surge voltage and transient spike voltage in the circuit, lightning proof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage proof, and improve shock resistance.
Transmission Distance Up To 1.2km
The USB Signal Can Be Converted Into A Balanced Differential RS485/422 Signal And The Transmission Rate Is Stable. The Transmission Distance Is About 1.2km For RS485/422 And About 5 Meters For USB.
Multi-System Support
Supports Mac, Linux, Android, WinCE, Win11/10/8.1/8/7/XP, Etc.
