USB to RS232 / RS485 / TTL Industrial Isolated Converter

This is an industrial USB to RS232/485/TTL isolated converter with original FT232RL inside. It features embedded protection circuits such as power isolation, ADI magnetically isolation, and TVS diode, etc. What’s more, the USB TO RS232/485/TTL comes with an aluminum alloy enclosure, make it solid and durable to work.

The USB TO RS232/485/TTL is very easy to use, fully automatic transceiving without delay. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment and/or applications with high communication requirement.

Package: USB TO RS232/485/TTL x 1 and USB cable x 1

USB TO RS232, USB TO RS485, USB TO TTL (UART)

Adopt original FT232RL, fast communicating, stable and reliable, better compatibility

Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal

Onboard unibody magnetical 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, lightning-proof & anti-electrostatic

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 each other

Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch

Aluminium alloy enclosure with sand blasting and anodic oxidation, CNC process opening, solid and durable

3 LEDs for indicating the power and transceiver status

High quality USB-B and RS232 connectors, smoothly plug/pull
