USB To 4-Ch RS232

FT4232HL | Stable Transmission | Multiple Devices Applicable | Multi-OS Compatible

Features At A Glance

• Adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility
• Supports USB to 4-ch isolated RS232, convenient for expanding multiple RS232 industrial serial devices
• Onboard unibody power supply isolation, provides stable isolated voltage
• Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection
• Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock proof performance
• Onboard power supply screw terminal, allows 5V~36V DC wide range input
• 9 LEDs for indicating the power and transceiver status
• Aluminum alloy enclosure with sand blasting and anodic oxidation, solid and durable
