LORDWORLD Industrial Isolated USB to RS232/485 Converter FT4232HL development board

SKU CH-ZTW4-9C89K

Industrial isolated converter uses an FT4232HL chip to provide four RS232 ports, two RS232 ports with power isolation, or two RS232/485 ports with digital isolation.

  • Four-channel RS232 via original FT4232HL chip for fast, stable communication
  • Two-channel RS232 with onboard power isolation, no extra supply needed for isolated terminal
  • Two-channel RS232/485 with digital isolation for high reliability and strong anti-interference
  • Onboard TVS suppressor protects against surge, transient spikes, lightning and ESD
  • Self-recovery fuse and protection diodes ensure stable outputs with over-current and over-voltage proof

Industrial USB to Multi-Serial Converter

This development board converts a single USB connection into four independent RS232 channels or configurable combinations of RS232 and RS485 ports. It is built around the original FT4232HL bridge chip for stable, high-speed communication in industrial automation, test rigs and embedded development.

Suited for engineers needing multiple isolated

The board provides onboard power-supply isolation for two RS232 channels and digital signal isolation for two RS232/485 channels, removing ground-loop problems in noisy environments. Buyers who require only a single non-isolated port or need USB-to-Ethernet conversion should consider other devices.

Four-channel FT4232HL bridge with dual isolation

The FT4232HL chip drives all four channels simultaneously while integrated TVS diodes, a self-recovery fuse and protection diodes guard against transients and over-current events. This combination of channel count, isolation scheme and on-board protection determines whether the module matches your application.

商品問答

How many serial channels does the FT4232HL chip provide on this board?

The FT4232HL supports four RS232 channels or two RS232 channels plus two RS232/485 channels from a single USB connection.

What isolation does the board use for the RS232/485 ports?

Onboard unibody digital isolation separates the signals for the RS232/485 channels, giving high reliability and strong anti-interference performance.

What protection components are fitted to the terminal side?

TVS diodes suppress surge and transient spike voltage, while a self-recovery fuse and protection diodes guard against over-current and over-voltage events.
