USB TO RS232 / RS485 / TTL Industrial Isolated Converter

USB to RS232/485/TTL Interface Converter, Industrial Isolation

Overview

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 magnetical isolation, and TVS diode, etc. What's more, the USB TO RS232/485/TTL comes with an aluminium 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 equipments and/or applications with high communication requirement.

Features 

• 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
