Description

USB TO RS232/485/422/TTL, an industrial-grade isolated converter, adopts the original FT232RNL, built-in protection circuits including power isolation, ADI magnetical isolation and TVS, and with aluminum alloy shell design. USB TO RS232/485/422/TTL is easy to operate and features an automatic transmission and reception conversion with zero delays. Also, it has the characteristics of fast communication speed, stability, reliability, safety, etc., and can be applied to various industrial control device or applications with high communication requirements.

Features:

1. Adopt the original FT232RNL chip, fast communicating, is stable, and reliable, better compatibility
2. Supports multiple communication interface conversion: USB to RS232, USB to RS485, USB to RS422, USB to TTL
3. Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
4. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
5. Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning proof & ESD protection
6. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock resistance
7. A fully automatic transceiver circuit with no delay ensures the USB port communicates with different interfaces fastly and stably, without interfering with each other
8. Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch
9. 3 LEDs for indicating the power and transceiver status
10. High-quality USB-B and RS232 connectors, smoothly plug/pull
11. Industrial grade metal case supports wall-mount and rail-mount installations, solid and beautiful, easy to install
