Industrial Isolated USB to RS232/485 Converter
A high-end industrial signal converter from USB to RS232 and RS485, based on the genuine FT232RNL chip. The device ensures fast and stable communication, and thanks to built-in galvanic isolation for power and signals, as well as multi-level protection (lightning, surge, ESD), it is an ideal solution for industrial automation applications and systems requiring high reliability.
Key Features:
- Based on the genuine FT232RNL chip.
- Built-in galvanic power isolation.
- Integrated digital signal isolation.
- Built-in TVS (Transient Voltage Suppressor) circuit – effectively suppresses surges and voltage spikes in the circuit.
- Self-resetting fuse and protective diodes ensure stable current-voltage outputs, protecting against overcurrent and overvoltage.
- Built-in terminal resistor 120R for the RS485 interface, activated/deactivated via jumper.
- Three LED indicators for power status and data transmission.
- Industrial ABS enclosure, suitable for mounting on a DIN rail.
Based on Genuine Chip
The use of the genuine FT232RNL chip ensures better stability and compatibility.
Galvanically Isolated Design
Built-in power and signal isolation provides stable, isolated voltage, high reliability, strong interference immunity, and low power consumption.
Multi-level Protection – Safety and Stability
The TVS circuit, self-resetting fuse, and protective diodes effectively shield the device from surges, overcurrents, and electrostatic discharge.
