Industrial Isolated USB To RS232/485 Converter, Original FT4232HL Chip, Supports USB To 2-Ch RS232 + 2-Ch RS232/485
USB TO 4CH RS232/485 is an industrial isolated USB to RS232/485 converter, adopts the original FT4232HL chip, with protection circuits such as built-in power isolation, ADI magnetical isolation, and TVS, and aluminum alloy case design. It is easy to operate with a zero-delay fully automatic transceiver circuit and features fast communication speed, stability, reliability, and security, which is suitable for industrial devices and applications with high communication requirements.
Features
- Adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility.
- Supports USB to RS232, USB to RS485.
- 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, and low power consumption.
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightningproof and ESD protection.
- Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, and improve shockproof performance.
- Built-in 120ohm resistance on RS485 output interfaces, and users can enable it through a DIP switch, easy and flexible.
- 9 LEDs for indicating the power, debugging status, and transceiver status.
- Industrial grade metal case, supports wall-mount and rail-mount installation, solid and beautiful, easy to install.
