This USB to 2-Channel RS485 converter is made for strong communication with its original FT2232HL chip, providing fast, stable, and reliable data transfer. It supports dual independent RS485 channels, each capable of concurrent communication.
The converter features built-in power supply isolation, eliminating the need for an extra power source for the isolated terminal, and digital isolation for low power consumption. Additionally, it includes a Transient Voltage Suppressor (TVS) to protect against surge and transient spike voltages, making it lightning-proof and anti-electrostatic.
Features
- Adopts original FT2232HL chip, fast communication, stable and reliable, better compatibility
- Extending USB to 2CH RS485, allows concurrent and independent communication for each channel
- Unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
- Unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
- Onboard self-recovery fuse and protection diodes, gives the current/voltage stable outputs, provides over-current/over-voltage proof, improves shockproof performance
- Built-in 120R terminal resistor on the RS485 ports, configurable via jumper for flexible switching
- 3 LEDs for indicating the power and transceiver status
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
