USB TO RS232/485/422/TTL Interface Converter, Industrial Isolation

Description: This is an industrial USB to RS232/485/422/TTL isolated converter with original FT232RNL inside. 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, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance.

Features:

• Adopt original FT232RNL chip, fast communicating, stable and reliable, better compatibility
• Supports multiple communication interface conversion: USB to RS232, USB to RS485, USB to RS422, USB to TTL
• Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
• 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, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
• Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering with each other
• Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch
• 3 LEDs for indicating the power and transceiver status
• High quality USB-B and RS232 connectors, smoothly plug/pull
• Industrial grade metal case, supports wall-mount and rail-mount installations, solid and beautiful, easy to install
