LORDWORLD USB to 2CH RS485 Isolated Converter FT2232HL Development Board

SKU CH-JZKX-GA3KP

Industrial-grade USB to dual RS485 converter with onboard FT2232HL chip, power isolation, TVS protection, self-recovery fuse, configurable 120R termination and rail-mount ABS case

  • Concurrent dual-channel RS485 communication via FT2232HL chip
  • Integrated power isolation removes need for external isolated supply
  • Digital signal isolation delivers high reliability and strong anti-interference
  • Onboard TVS protection suppresses surge and transient spike voltages
  • Self-recovery fuse with diodes provides over-current and over-voltage proof

Two-channel RS485 adapter

This USB to RS485 converter adds two independent serial channels to a host computer. It is aimed at engineers and technicians who need reliable Modbus or custom protocol links in industrial or automation projects. The onboard FT2232HL chip handles the USB-to-serial translation without extra drivers on most modern operating systems.

Integrated isolation and protection

Each channel carries its own power and digital isolation so ground loops and noise do not corrupt data. Onboard TVS devices clamp surge and transient spikes while a self-recovery fuse and protection diodes guard against over-current and over-voltage events. A 120 ohm termination resistor is fitted on each port and can be enabled or disabled with a jumper for bus matching.

Rail-mount enclosure simplifies setup

The small ABS case clips onto a standard DIN rail so the board sits securely inside a cabinet. Three status LEDs show power and per-channel transmit and receive activity for quick diagnostics. Installers who need screw-terminal blocks or software-configurable baud rates will find those features absent and should plan accordingly.

Perguntas sobre este artigo

Will the 120R termination jumper or the TVS diodes need periodic replacement?

The 120R termination resistor is built into the RS485 ports and switched by a jumper; it is a passive component with no wear-out mechanism. The TVS diodes and self-recovery fuse are solid-state protection devices that reset automatically after a transient event and do not require scheduled replacement.

What limits sustained throughput on each RS485 channel?

Each channel is driven by the onboard FT2232HL chip, so the practical ceiling is the USB signalling rate and the RS485 line speed you configure; the converter itself imposes no additional bottleneck beyond those two factors.

How much heat does the board produce when both channels run continuously?

The manufacturer highlights low power consumption and an onboard unibody isolated supply; with no active cooling fitted, the ABS rail-mount case relies on natural convection, so the board stays warm but not hot during all-day operation.
